Circle and Points\n\nInput\n\nThe input consists of a series of data sets, followed by a single line\nonly containing a single character '0', which indicates the end of the\ninput. Each data set begins with a line containing an integer N,\nwhich indicates the number of points in the data set. It is\nfollowed by N lines describing the coordinates of the\npoints. Each of the N lines has two decimal fractions X\nand Y, describing the x- and y-coordinates of a\npoint, respectively. They are given with five digits after the decimal\npoint.\n\nYou may assume 1 <= N <= 300, 0.0 <= X <= 10.0, and 0.0\n<= Y <= 10.0. No two points are closer than 0.0001. No two\npoints in a data set are approximately at a distance of 2.0. More\nprecisely, for any two points in a data set, the distance d\nbetween the two never satisfies 1.9999 <= d <= 2.0001. Finally,\nno three points in a data set are simultaneously very close to a\nsingle circle of radius one. More precisely,\nlet P1, P2, and P3 be any three points in a\ndata set, and d1, d2, and d3\nthe distances from an arbitrarily selected point in the xy-plane to each of them\nrespectively. Then it never simultaneously holds that 0.9999 <=\ndi <= 1.0001 (i = 1, 2, 3).\n\nOutput\n\nFor each data set, print a single line containing the maximum number\nof points in the data set that can be simultaneously enclosed by a\ncircle of radius one. No other characters including leading and\ntrailing spaces should be printed.\n\nSample Input\n\n3\n6.47634 7.69628\n5.16828 4.79915\n6.69533 6.20378\n6\n7.15296 4.08328\n6.50827 2.69466\n5.91219 3.86661\n5.29853 4.16097\n6.10838 3.46039\n6.34060 2.41599\n8\n7.90650 4.01746\n4.10998 4.18354\n4.67289 4.01887\n6.33885 4.28388\n4.98106 3.82728\n5.12379 5.16473\n7.84664 4.67693\n4.02776 3.87990\n20\n6.65128 5.47490\n6.42743 6.26189\n6.35864 4.61611\n6.59020 4.54228\n4.43967 5.70059\n4.38226 5.70536\n5.50755 6.18163\n7.41971 6.13668\n6.71936 3.04496\n5.61832 4.23857\n5.99424 4.29328\n5.60961 4.32998\n6.82242 5.79683\n5.44693 3.82724\n6.70906 3.65736\n7.89087 5.68000\n6.23300 4.59530\n5.92401 4.92329\n6.24168 3.81389\n6.22671 3.62210\n0\n\nOutput for the Sample Input\n\n2\n5\n5\n11", "split": "validation", "target_descriptions": {"code_size_bytes": "Submitted source-code file size, in bytes.", "cpu_time_ms": "Execution CPU time reported by official Project CodeNet metadata, in milliseconds.", "memory_kb": "Peak memory usage reported by official Project CodeNet metadata, in kilobytes."}, "targets": {"code_size_bytes": 1632, "cpu_time_ms": 20000, "memory_kb": 105860}, "variant": "medium_resource"} +{"dataset": "codeNet", "domain": "code_generation", "example_id": "codeNet:Haskell:s780949783", "group_id": "codeNet:p00723", "input_text": "import Data.List\n\nf s n = \n let s1 = take n s\n s2 = drop n s\n r1 = reverse s1\n r2 = reverse s2\n in\n [s1++s2, s1++r2, r1++s2, r1++r2, s2++s1, s2++r1, r2++s1, r2++r1]\n\n\nans s =\n let l = length s\n p = nub $ sort $ concat $ map (f s) [1..(l-1)]\n in\n length p\n\n\nmain = do\n _ <- getLine\n c <- getContents\n let i = lines c\n o = map ans i\n mapM_ print o\n\n", "language": "Haskell", "metadata": {"date": 1550759127, "filename_ext": "hs", "original_language": "Haskell", "problem_description_relpath": "problem_descriptions/p00723.html", "problem_id": "p00723", "resource_group": "medium_resource", "sample_input_relpath": "derived/input_output/data/p00723/input.txt", "sample_output_relpath": "derived/input_output/data/p00723/output.txt", "source_dataset": "Project CodeNet", "source_relpath": "data/p00723/Haskell/s780949783.hs", "split_policy": "Global OOD problem IDs are disjoint from train, validation, and in-distribution test problem IDs.", "status": "Accepted", "submission_id": "s780949783", "user_id": "u133119785"}, "prompt_components": {"gold_output": "1\n6\n12\n18\n", "input_to_evaluate": "import Data.List\n\nf s n = \n let s1 = take n s\n s2 = drop n s\n r1 = reverse s1\n r2 = reverse s2\n in\n [s1++s2, s1++r2, r1++s2, r1++r2, s2++s1, s2++r1, r2++s1, r2++r1]\n\n\nans s =\n let l = length s\n p = nub $ sort $ concat $ map (f s) [1..(l-1)]\n in\n length p\n\n\nmain = do\n _ <- getLine\n c <- getContents\n let i = lines c\n o = map ans i\n mapM_ print o\n\n", "problem_context": "Problem B: Organize Your Train part II\n\nRJ Freight, a Japanese railroad company for freight operations\nhas recently constructed exchange lines at Hazawa, Yokohama.\nThe layout of the lines is shown in Figure B-1.\n\nFigure B-1: Layout of the exchange lines\n\nA freight train consists of 2 to 72 freight cars.

In subsequent steps, start from the slot of the stone removed in the last step, make k hops clockwise on the remaining stones and remove the one you reach. In other words, skip (k - 1) remaining stones clockwise and remove the next one. Repeat this until only one stone is left and answer its number.\n\nFor example, the answer for the case n = 8, k = 5, m = 3 is 1, as shown in Figure 1.\n\nFigure 1: An example game\n\nInitial state: Eight stones are arranged on a circle.\n\nStep 1: Stone 3 is removed since m = 3.\n\nStep 2: You start from the slot that was occupied by stone 3. You skip four stones 4, 5, 6 and 7 (since k = 5), and remove the next one, which is 8.\n\nStep 3: You skip stones 1, 2, 4 and 5, and thus remove 6. Note that you only count stones that are still on the circle and ignore those already removed. Stone 3 is ignored in this case.\n\nSteps 4-7: You continue until only one stone is left. Notice that in later steps when only a few stones remain, the same stone may be skipped multiple times. For example, stones 1 and 4 are skipped twice in step 7.\n\nFinal State: Finally, only one stone, 1, is on the circle. This is the final state, so the answer is 1.\n\nInput\n\nThe input consists of multiple datasets each of which is formatted as follows.\n\nn k m\n\nThe last dataset is followed by a line containing three zeros.

Thus a search tree can be used both as a dictionary and as a priority queue.\n\nBinary search tree is one of fundamental search trees. The keys in a binary search tree are always stored in such a way as to satisfy the following binary search tree property:\n\nLet $x$ be a node in a binary search tree. If $y$ is a node in the left subtree of $x$, then $y.key \\leq x.key$. If $y$ is a node in the right subtree of $x$, then $x.key \\leq y.key$.\n\nThe following figure shows an example of the binary search tree.\n\nFor example, keys of nodes which belong to the left sub-tree of the node containing 80 are less than or equal to 80, and keys of nodes which belong to the right sub-tree are more than or equal to 80. The binary search tree property allows us to print out all the keys in the tree in sorted order by an inorder tree walk.\n\nA binary search tree should be implemented in such a way that the binary search tree property continues to hold after modifications by insertions and deletions. A binary search tree can be represented by a linked data structure in which each node is an object. In addition to a key field and satellite data, each node contains fields left, right, and p that point to the nodes corresponding to its left child, its right child, and its parent, respectively.\n\nTo insert a new value $v$ into a binary search tree $T$, we can use the procedure insert as shown in the following pseudo code. The insert procedure is passed a node $z$ for which $z.key = v$, $z.left = NIL$, and $z.right = NIL$. The procedure modifies $T$ and some of the fields of $z$ in such a way that $z$ is inserted into an appropriate position in the tree.\n\n1 insert(T, z)\n2 y = NIL // parent of x\n3 x = 'the root of T'\n4 while x ≠ NIL\n5 y = x // set the parent\n6 if z.key < x.key\n7 x = x.left // move to the left child\n8 else\n9 x = x.right // move to the right child\n10 z.p = y\n11\n12 if y == NIL // T is empty\n13 'the root of T' = z\n14 else if z.key < y.key\n15 y.left = z // z is the left child of y\n16 else\n17 y.right = z // z is the right child of y\n\nWrite a program which performs the following operations to a binary search tree $T$.\n\ninsert $k$: Insert a node containing $k$ as key into $T$.\n\nprint: Print the keys of the binary search tree by inorder tree walk and preorder tree walk respectively.\n\nYou should use the above pseudo code to implement the insert operation. $T$ is empty at the initial state.\n\nInput\n\nIn the first line, the number of operations $m$ is given.

(See Notes for the description of Rock Paper Scissors. A draw also counts as a round.)\n\nEach time the player wins a round, depending on which hand he/she uses, he/she earns the following score (no points for a draw or a loss):\n\nR points for winning with Rock;\n\nS points for winning with Scissors;\n\nP points for winning with Paper.\n\nHowever, in the i-th round, the player cannot use the hand he/she used in the (i-K)-th round. (In the first K rounds, the player can use any hand.)\n\nBefore the start of the game, the machine decides the hand it will play in each round.

Takahashi the merchant is going on a travel from town 1 to town N, buying and selling apples.\n\nTakahashi will begin the travel at town 1, with no apple in his possession. The actions that can be performed during the travel are as follows:\n\nMove: When at town i (i < N), move to town i + 1.\n\nMerchandise: Buy or sell an arbitrary number of apples at the current town. Here, it is assumed that one apple can always be bought and sold for A_i yen (the currency of Japan) at town i (1 ≦ i ≦ N), where A_i are distinct integers. Also, you can assume that he has an infinite supply of money.\n\nFor some reason, there is a constraint on merchandising apple during the travel: the sum of the number of apples bought and the number of apples sold during the whole travel, must be at most T. (Note that a single apple can be counted in both.)\n\nDuring the travel, Takahashi will perform actions so that the profit of the travel is maximized. Here, the profit of the travel is the amount of money that is gained by selling apples, minus the amount of money that is spent on buying apples. Note that we are not interested in apples in his possession at the end of the travel.\n\nAoki, a business rival of Takahashi, wants to trouble Takahashi by manipulating the market price of apples. Prior to the beginning of Takahashi's travel, Aoki can change A_i into another arbitrary non-negative integer A_i' for any town i, any number of times. The cost of performing this operation is |A_i - A_i'|. After performing this operation, different towns may have equal values of A_i.\n\nAoki's objective is to decrease Takahashi's expected profit by at least 1 yen.
