Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. This is an interactive problem You are given a grid nΓ— n, where n is odd. Rows are enumerated from 1 to n from up to down, columns are enumerated from 1 to n from left to right. Cell, standing on the intersection of row x and column y, is denoted by (x, y). Every cell contains 0 or 1. It is known that the top-left cell contains 1, and the bottom-right cell contains 0. We want to know numbers in all cells of the grid. To do so we can ask the following questions: "? x_1 y_1 x_2 y_2", where 1 ≀ x_1 ≀ x_2 ≀ n, 1 ≀ y_1 ≀ y_2 ≀ n, and x_1 + y_1 + 2 ≀ x_2 + y_2. In other words, we output two different cells (x_1, y_1), (x_2, y_2) of the grid such that we can get from the first to the second by moving only to the right and down, and they aren't adjacent. As a response to such question you will be told if there exists a path between (x_1, y_1) and (x_2, y_2), going only to the right or down, numbers in cells of which form a palindrome. For example, paths, shown in green, are palindromic, so answer for "? 1 1 2 3" and "? 1 2 3 3" would be that there exists such path. However, there is no palindromic path between (1, 1) and (3, 1). <image> Determine all cells of the grid by asking not more than n^2 questions. It can be shown that the answer always exists. Input The first line contains odd integer (3 ≀ n < 50) β€” the side of the grid. Interaction You begin the interaction by reading n. To ask a question about cells (x_1, y_1), (x_2, y_2), in a separate line output "? x_1 y_1 x_2 y_2". Numbers in the query have to satisfy 1 ≀ x_1 ≀ x_2 ≀ n, 1 ≀ y_1 ≀ y_2 ≀ n, and x_1 + y_1 + 2 ≀ x_2 + y_2. Don't forget to 'flush', to get the answer. In response, you will receive 1, if there exists a path going from (x_1, y_1) to (x_2, y_2) only to the right or down, numbers in cells of which form a palindrome, and 0 otherwise. In case your query is invalid or you asked more than n^2 queries, program will print -1 and will finish interaction. You will receive Wrong answer verdict. Make sure to exit immediately to avoid getting other verdicts. When you determine numbers in all cells, output "!". Then output n lines, the i-th of which is a string of length n, corresponding to numbers in the i-th row of the grid. After printing a query do not forget to output end of line and flush the output. Otherwise, you will get Idleness limit exceeded. To do this, use: * fflush(stdout) or cout.flush() in C++; * System.out.flush() in Java; * flush(output) in Pascal; * stdout.flush() in Python; * see documentation for other languages. Hack Format To hack, use the following format. The first line should contain a single odd integer n (side of your grid). The i-th of n following lines should contain a string of length n corresponding to the i-th row of the grid. Top left element of the grid has to be equal to 1, bottom right has to be equal to 0. Example Input 3 0 1 0 1 1 1 1 Output ? 1 1 1 3 ? 1 1 2 3 ? 2 1 2 3 ? 3 1 3 3 ? 2 2 3 3 ? 1 2 3 2 ? 1 2 3 3 ! 100 001 000 Submitted Solution: ``` from sys import stdout def full(k, get, mass): global l # print(f"k = {k}") if k%2 == 1: k = k else: k = k-1 if k-4 >= 0: for i in range(l)[k-4::-2]: answer = ask(get(i), get(i+2)) if answer: mass[i] = mass[i+2] else: mass[i] = not mass[i+2] # print((k+2)) # print(2*n-1) if (k+2) < (2*n-1): # print("pass here") for i in range(l)[k+2::2]: # print(f"l = {l}, i = {i}") answer = ask(get(i-2), get(i)) if answer: mass[i] = mass[i-2] else: mass[i] = not mass[i-2] def ask(x, y): x = [x[1], x[0]] y = [y[1], y[0]] q = f"? {x[0]+1} {x[1]+1} {y[0]+1} {y[1]+1}" print(q) stdout.flush() answer = bool(int(input())) return answer def get_top(idx): if idx>=n: i = n-1 j = idx%n+1 else: i = idx%n j = 0 return i,j def get_bot(idx): if idx>=n: j = n-1 i = idx%n+1 else: j = idx%n i = 0 return i,j def fun( mass, f): l = len(mass) get = f for i in range(l)[2:l-1:2]: answer = ask(get(i-2), get(i)) # print(f"answer = {answer}") if answer: mass[i] = mass[i-2] else: mass[i] = not mass[i-2] # print(mass) for i in range(l)[4::2]: if (mass[i-4] == mass[i-2]) and (mass[i-2] != mass[i]): answer = ask(get(i-3), get(i-1)) if answer: answer = ask(get(i-4), get(i-1)) if answer: mass[i-3] = mass[i-4] mass[i-1] = mass[i-4] else: mass[i-3] = not mass[i-4] mass[i-1] = not mass[i-4] full(i-1, get, mass) else: answer = ask(get(i-3), get(i)) if answer: mass[i-3] = mass[i] mass[i-1] = mass[i-2] else: mass[i-3] = not mass[i] mass[i-1] = not mass[i-2] full(i, get, mass) break elif (mass[i-4] != mass[i-2]) and (mass[i-2] == mass[i]): answer = ask(get(i-3), get(i-1)) if answer: answer = ask(get(i-3), get(i)) if answer: mass[i-3] = mass[i] mass[i-1] = mass[i] else: mass[i-3] = not mass[i] mass[i-1] = not mass[i] full(i, get, mass) else: answer = ask(get(i-4), get(i-1)) if answer: mass[i-3] = mass[i-2] mass[i-1] = mass[i-4] else: mass[i-3] = not mass[i-2] mass[i-1] = not mass[i-4] full(i-1, get, mass) break if __name__ == "__main__": n = int(input()) a_top = [None]*(2*n-1) a_top[0] = True a_top[len(a_top)-1] = False a_bot = a_top.copy() l = len(a_bot) fun(a_top, get_top) # print(a_top) fun(a_bot, get_bot) # print(a_bot) matrix = [] for i in range(n): matrix.append([None]*n) for i in range(len(a_top)): idx = get_top(i)[::-1] # print("idx_top", idx) matrix[idx[0]][idx[1]] = a_top[i] idx = get_bot(i)[::-1] # print("idx_bot", idx) matrix[idx[0]][idx[1]] = a_bot[i] for i in range(n)[1:n-1:1]: for j in range(n)[1:n-1:1]: answer = ask([j-1,i-1], [j,i]) if answer: matrix[i][j] = matrix[i-1][j-1] else: matrix[i][j] = not matrix[i-1][j-1] print("!") for i in matrix: for j in i: print(int(j), end = "") print() stdout.flush() ```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. This is an interactive problem You are given a grid nΓ— n, where n is odd. Rows are enumerated from 1 to n from up to down, columns are enumerated from 1 to n from left to right. Cell, standing on the intersection of row x and column y, is denoted by (x, y). Every cell contains 0 or 1. It is known that the top-left cell contains 1, and the bottom-right cell contains 0. We want to know numbers in all cells of the grid. To do so we can ask the following questions: "? x_1 y_1 x_2 y_2", where 1 ≀ x_1 ≀ x_2 ≀ n, 1 ≀ y_1 ≀ y_2 ≀ n, and x_1 + y_1 + 2 ≀ x_2 + y_2. In other words, we output two different cells (x_1, y_1), (x_2, y_2) of the grid such that we can get from the first to the second by moving only to the right and down, and they aren't adjacent. As a response to such question you will be told if there exists a path between (x_1, y_1) and (x_2, y_2), going only to the right or down, numbers in cells of which form a palindrome. For example, paths, shown in green, are palindromic, so answer for "? 1 1 2 3" and "? 1 2 3 3" would be that there exists such path. However, there is no palindromic path between (1, 1) and (3, 1). <image> Determine all cells of the grid by asking not more than n^2 questions. It can be shown that the answer always exists. Input The first line contains odd integer (3 ≀ n < 50) β€” the side of the grid. Interaction You begin the interaction by reading n. To ask a question about cells (x_1, y_1), (x_2, y_2), in a separate line output "? x_1 y_1 x_2 y_2". Numbers in the query have to satisfy 1 ≀ x_1 ≀ x_2 ≀ n, 1 ≀ y_1 ≀ y_2 ≀ n, and x_1 + y_1 + 2 ≀ x_2 + y_2. Don't forget to 'flush', to get the answer. In response, you will receive 1, if there exists a path going from (x_1, y_1) to (x_2, y_2) only to the right or down, numbers in cells of which form a palindrome, and 0 otherwise. In case your query is invalid or you asked more than n^2 queries, program will print -1 and will finish interaction. You will receive Wrong answer verdict. Make sure to exit immediately to avoid getting other verdicts. When you determine numbers in all cells, output "!". Then output n lines, the i-th of which is a string of length n, corresponding to numbers in the i-th row of the grid. After printing a query do not forget to output end of line and flush the output. Otherwise, you will get Idleness limit exceeded. To do this, use: * fflush(stdout) or cout.flush() in C++; * System.out.flush() in Java; * flush(output) in Pascal; * stdout.flush() in Python; * see documentation for other languages.

Provide tags and a correct Python 3 solution for this coding contest problem. One day Vasya was going home when he saw a box lying on the road. The box can be represented as a rectangular parallelepiped. Vasya needed no time to realize that the box is special, as all its edges are parallel to the coordinate axes, one of its vertices is at point (0, 0, 0), and the opposite one is at point (x1, y1, z1). The six faces of the box contain some numbers a1, a2, ..., a6, exactly one number right in the center of each face. <image> The numbers are located on the box like that: * number a1 is written on the face that lies on the ZOX plane; * a2 is written on the face, parallel to the plane from the previous point; * a3 is written on the face that lies on the XOY plane; * a4 is written on the face, parallel to the plane from the previous point; * a5 is written on the face that lies on the YOZ plane; * a6 is written on the face, parallel to the plane from the previous point. At the moment Vasya is looking at the box from point (x, y, z). Find the sum of numbers that Vasya sees. Note that all faces of the box are not transparent and Vasya can't see the numbers through the box. The picture contains transparent faces just to make it easier to perceive. You can consider that if Vasya is looking from point, lying on the plane of some face, than he can not see the number that is written on this face. It is enough to see the center of a face to see the corresponding number for Vasya. Also note that Vasya always reads correctly the ai numbers that he sees, independently of their rotation, angle and other factors (that is, for example, if Vasya sees some ai = 6, then he can't mistake this number for 9 and so on). Input The fist input line contains three space-separated integers x, y and z (|x|, |y|, |z| ≀ 106) β€” the coordinates of Vasya's position in space. The second line contains three space-separated integers x1, y1, z1 (1 ≀ x1, y1, z1 ≀ 106) β€” the coordinates of the box's vertex that is opposite to the vertex at point (0, 0, 0). The third line contains six space-separated integers a1, a2, ..., a6 (1 ≀ ai ≀ 106) β€” the numbers that are written on the box faces.

Provide tags and a correct Python 3 solution for this coding contest problem. One day Vasya was going home when he saw a box lying on the road. The box can be represented as a rectangular parallelepiped. Vasya needed no time to realize that the box is special, as all its edges are parallel to the coordinate axes, one of its vertices is at point (0, 0, 0), and the opposite one is at point (x1, y1, z1). The six faces of the box contain some numbers a1, a2, ..., a6, exactly one number right in the center of each face. <image> The numbers are located on the box like that: * number a1 is written on the face that lies on the ZOX plane; * a2 is written on the face, parallel to the plane from the previous point; * a3 is written on the face that lies on the XOY plane; * a4 is written on the face, parallel to the plane from the previous point; * a5 is written on the face that lies on the YOZ plane; * a6 is written on the face, parallel to the plane from the previous point. At the moment Vasya is looking at the box from point (x, y, z). Find the sum of numbers that Vasya sees. Note that all faces of the box are not transparent and Vasya can't see the numbers through the box. The picture contains transparent faces just to make it easier to perceive. You can consider that if Vasya is looking from point, lying on the plane of some face, than he can not see the number that is written on this face. It is enough to see the center of a face to see the corresponding number for Vasya. Also note that Vasya always reads correctly the ai numbers that he sees, independently of their rotation, angle and other factors (that is, for example, if Vasya sees some ai = 6, then he can't mistake this number for 9 and so on). Input The fist input line contains three space-separated integers x, y and z (|x|, |y|, |z| ≀ 106) β€” the coordinates of Vasya's position in space. The second line contains three space-separated integers x1, y1, z1 (1 ≀ x1, y1, z1 ≀ 106) β€” the coordinates of the box's vertex that is opposite to the vertex at point (0, 0, 0).

Note that all faces of the box are not transparent and Vasya can't see the numbers through the box. The picture contains transparent faces just to make it easier to perceive. You can consider that if Vasya is looking from point, lying on the plane of some face, than he can not see the number that is written on this face. It is enough to see the center of a face to see the corresponding number for Vasya. Also note that Vasya always reads correctly the ai numbers that he sees, independently of their rotation, angle and other factors (that is, for example, if Vasya sees some ai = 6, then he can't mistake this number for 9 and so on). Input The fist input line contains three space-separated integers x, y and z (|x|, |y|, |z| ≀ 106) β€” the coordinates of Vasya's position in space. The second line contains three space-separated integers x1, y1, z1 (1 ≀ x1, y1, z1 ≀ 106) β€” the coordinates of the box's vertex that is opposite to the vertex at point (0, 0, 0). The third line contains six space-separated integers a1, a2, ..., a6 (1 ≀ ai ≀ 106) β€” the numbers that are written on the box faces. It is guaranteed that point (x, y, z) is located strictly outside the box. Output Print a single integer β€” the sum of all numbers on the box faces that Vasya sees. Examples Input 2 2 2 1 1 1 1 2 3 4 5 6 Output 12 Input 0 0 10 3 2 3 1 2 3 4 5 6 Output 4 Note The first sample corresponds to perspective, depicted on the picture. Vasya sees numbers a2 (on the top face that is the darkest), a6 (on the right face that is the lightest) and a4 (on the left visible face). In the second sample Vasya can only see number a4. Submitted Solution: ``` x,y,z=list(map(int,input().split())) x1,y1,z1=list(map(int,input().split())) a=list(map(int,input().split())) b=0 if y<0: b+=a[0] if y>y1: b+=a[1] if z<0: b+=a[2] if z>z1: b+=a[3] if x<0: b+=a[4] if x>x1: b+=a[5] print(b) ```

Examples Input 2 2 2 1 1 1 1 2 3 4 5 6 Output 12 Input 0 0 10 3 2 3 1 2 3 4 5 6 Output 4 Note The first sample corresponds to perspective, depicted on the picture. Vasya sees numbers a2 (on the top face that is the darkest), a6 (on the right face that is the lightest) and a4 (on the left visible face). In the second sample Vasya can only see number a4.

Provide tags and a correct Python 3 solution for this coding contest problem. Flatland has recently introduced a new type of an eye check for the driver's licence. The check goes like that: there is a plane with mannequins standing on it. You should tell the value of the minimum angle with the vertex at the origin of coordinates and with all mannequins standing inside or on the boarder of this angle. As you spend lots of time "glued to the screen", your vision is impaired. So you have to write a program that will pass the check for you. Input The first line contains a single integer n (1 ≀ n ≀ 105) β€” the number of mannequins. Next n lines contain two space-separated integers each: xi, yi (|xi|, |yi| ≀ 1000) β€” the coordinates of the i-th mannequin. It is guaranteed that the origin of the coordinates has no mannequin. It is guaranteed that no two mannequins are located in the same point on the plane. Output Print a single real number β€” the value of the sought angle in degrees. The answer will be considered valid if the relative or absolute error doesn't exceed 10 - 6.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Flatland has recently introduced a new type of an eye check for the driver's licence. The check goes like that: there is a plane with mannequins standing on it. You should tell the value of the minimum angle with the vertex at the origin of coordinates and with all mannequins standing inside or on the boarder of this angle. As you spend lots of time "glued to the screen", your vision is impaired. So you have to write a program that will pass the check for you. Input The first line contains a single integer n (1 ≀ n ≀ 105) β€” the number of mannequins. Next n lines contain two space-separated integers each: xi, yi (|xi|, |yi| ≀ 1000) β€” the coordinates of the i-th mannequin. It is guaranteed that the origin of the coordinates has no mannequin. It is guaranteed that no two mannequins are located in the same point on the plane. Output Print a single real number β€” the value of the sought angle in degrees.

Provide tags and a correct Python 3 solution for this coding contest problem. You are given a rectangle grid. That grid's size is n Γ— m. Let's denote the coordinate system on the grid. So, each point on the grid will have coordinates β€” a pair of integers (x, y) (0 ≀ x ≀ n, 0 ≀ y ≀ m). Your task is to find a maximum sub-rectangle on the grid (x1, y1, x2, y2) so that it contains the given point (x, y), and its length-width ratio is exactly (a, b). In other words the following conditions must hold: 0 ≀ x1 ≀ x ≀ x2 ≀ n, 0 ≀ y1 ≀ y ≀ y2 ≀ m, <image>. The sides of this sub-rectangle should be parallel to the axes. And values x1, y1, x2, y2 should be integers. <image> If there are multiple solutions, find the rectangle which is closest to (x, y). Here "closest" means the Euclid distance between (x, y) and the center of the rectangle is as small as possible. If there are still multiple solutions, find the lexicographically minimum one. Here "lexicographically minimum" means that we should consider the sub-rectangle as sequence of integers (x1, y1, x2, y2), so we can choose the lexicographically minimum one. Input The first line contains six integers n, m, x, y, a, b (1 ≀ n, m ≀ 109, 0 ≀ x ≀ n, 0 ≀ y ≀ m, 1 ≀ a ≀ n, 1 ≀ b ≀ m).

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. You are given a rectangle grid. That grid's size is n Γ— m. Let's denote the coordinate system on the grid. So, each point on the grid will have coordinates β€” a pair of integers (x, y) (0 ≀ x ≀ n, 0 ≀ y ≀ m). Your task is to find a maximum sub-rectangle on the grid (x1, y1, x2, y2) so that it contains the given point (x, y), and its length-width ratio is exactly (a, b). In other words the following conditions must hold: 0 ≀ x1 ≀ x ≀ x2 ≀ n, 0 ≀ y1 ≀ y ≀ y2 ≀ m, <image>. The sides of this sub-rectangle should be parallel to the axes. And values x1, y1, x2, y2 should be integers. <image> If there are multiple solutions, find the rectangle which is closest to (x, y). Here "closest" means the Euclid distance between (x, y) and the center of the rectangle is as small as possible. If there are still multiple solutions, find the lexicographically minimum one. Here "lexicographically minimum" means that we should consider the sub-rectangle as sequence of integers (x1, y1, x2, y2), so we can choose the lexicographically minimum one. Input The first line contains six integers n, m, x, y, a, b (1 ≀ n, m ≀ 109, 0 ≀ x ≀ n, 0 ≀ y ≀ m, 1 ≀ a ≀ n, 1 ≀ b ≀ m). Output Print four integers x1, y1, x2, y2, which represent the founded sub-rectangle whose left-bottom point is (x1, y1) and right-up point is (x2, y2).
