Write Python code to solve the task. Little PandeyG is a curious student, studying in HEgwarts. Being smarter, faster and displaying more zeal for magic than any other student, one by one he managed to impress the three hidden witches of the school. They knew his secret desire to be a warrior, so each of them gave him ...
Step 1: To solve this problem, we need to find the minimum number of hits needed to defeat each enemy. Step 2: We can use dynamic programming to solve this problem. We can start by creating a list to store the minimum number of hits for each possible enemy strength. Step 3: We will then use dynamic programming to po...

Write Python code to solve the task. The Kingdom of Takahashi has N towns, numbered 1 through N. There is one teleporter in each town. The teleporter in Town i (1 \leq i \leq N) sends you to Town A_i. Takahashi, the king, loves the positive integer K. The selfish king wonders what town he will be in if he starts at T...
Step 1: The problem requires us to simulate the movement of the king as he uses teleporters to move to different towns. Step 2: We need to keep track of the town number he lands on after each teleport. Step 3: Once we detect a cycle in the sequence of towns visited, we can use that information to determine the town ...

Step 1: The problem requires us to calculate the number of candies Polycarp will buy based on the given constraints and his plan for visiting the booths. Step 2: We need to consider the initial amount of money Polycarp has, the prices of candies at each booth, and the process of buying candies according to Polycarp's...

Write Python code to solve the task. You are given an undirected graph consisting of n vertices and n edges. It is guaranteed that the given graph is connected (i. e. it is possible to reach any vertex from any other vertex) and there are no self-loops and multiple edges in the graph. Your task is to calculate the num...
Step 1: The problem calls for determining the number of simple paths of a given length in an undirected graph. This will require the implementation of an algorithm to traverse the graph and calculate the number of simple paths of each length. Also, we'll need to handle multiple test cases, so we should iterate throu...

Step 1: The problem can be solved using depth-first search (DFS) to find the simple paths in the undirected graph. We can start with implementing a DFS function to traverse the graph and count the number of paths. We also need to consider the handling of cycles and the number of paths required for each test case. We'...

Step 1: The logic of the code is to determine the outcome of the game given the words of Yaroslav and Andrey. The game finishes when no player can make a move. After the game is over, Yaroslav forms an integer from the characters written on his piece of paper. Then Andrey does the same. The resulting numbers can conta...

Write Python code to solve the task. Gennady is one of the best child dentists in Berland. Today n children got an appointment with him, they lined up in front of his office. All children love to cry loudly at the reception at the dentist. We enumerate the children with integers from 1 to n in the order they go in the...
Step 1: The problem requires checking the confidence level of the children after Gennady treats each child. Step 2: We need to check if the confidence levels of the children fall below zero and take necessary actions accordingly. Step 3: We also need to maintain information about the confidence levels and the seque...

Step 1: The problem requires simulating the process of Gennady treating the children's teeth in the correct order while handling their confidence levels and volume of their cries. Step 2: We need to iterate through the children in the line, decrease confidence levels based on the cry's volume, and handle chain reacti...

Write Python code to solve the task. As you very well know, the whole Universe traditionally uses three-dimensional Cartesian system of coordinates. In this system each point corresponds to three real coordinates (x, y, z). In this coordinate system, the distance between the center of the Universe and the point is calc...
Step 1: The problem requires finding the three real numbers (x, y, z) that maximize the distance from the center of the Universe in the metric of mushroom scientists. Step 2: The formula for the distance in the mushroom scientists' metric is xa·yb·zc, where the sum of x, y, z is at most S. Step 3: We need to normali...

Step 1: To solve this problem, we need to find the point (x, y, z) that maximizes the distance from the center of the Universe according to the mushroom scientists' metric. Step 2: We'll start by reading the input values for S and the three numbers a, b, and c. Step 3: Then we need to calculate the total of the thre...

Step 1: The problem requires us to find the coordinates (x, y, z) that maximize the distance to the center of the universe, based on the given metric. Step 2: We can calculate the total sum of the given metric values and use it to calculate the coordinates (x, y, z). Step 3: To meet the limitations, we need to ensur...

Write Python code to solve the task. A particular name-recording system is used by N employees of a firm. Everyday, they have to enter their names into the system. To make it easier to control the system, each employee has his/her name presented as a string of lowercase letters from 'a' to 'z' with the same length K. ...
Step 1: The problem requires finding the lexicographically minimal string that can be presented in the system to minimize the total amount of time spent by all employees. Step 2: We need to consider the name of each employee, the slots required to present the string, and the time it takes to rotate it. Step 3: We ha...

Write Python code to solve the task. — Hey folks, how do you like this problem? — That'll do it. BThero is a powerful magician. He has got n piles of candies, the i-th pile initially contains a_i candies. BThero can cast a copy-paste spell as follows: 1. He chooses two piles (i, j) such that 1 ≤ i, j ≤ n and i ≠...
Step 1: The problem asks us to find the maximum number of times BThero can cast the spell without losing his power. Step 2: We need to consider the conditions under which he loses his power and figure out the maximum number of times he can cast the spell before that happens. Step 3: We can start by parsing the inpu...
