だけ平行移動すると写真の中の位置になる．\n\n探したい星座の形と写真に写っている星の位置が与えられたとき，星座の座標を写真の中の座標に変換するために平行移動するべき量を答えるプログラムを書け．\n\n図 1: 探したい星座\n\n図 2: 星空の写真\n\n入力\n\n入力は複数のデータセットからなる．各データセットは以下の形式で与えられる．\n\n入力の 1 行目には探したい星座を構成する星の個数 m が書かれている．続く m 行には探したい星座を構成する m 個の星の x 座標と y 座標を示す整数が空白区切りで書かれている． m+2 行目には写真に写っている星の個数 n が書かれている．続く n 行には写真に写っている n 個の星の x 座標と y 座標を示す整数が空白区切りで書かれている．\n\n星座を構成する m 個の星の位置はすべて異なる．また，写真に写っている n 個の星の位置はすべて異なる． 1 ≤ m ≤ 200， 1 ≤ n ≤ 1000 である．星の x 座標と y 座標はすべて 0 以上 1000000 以下である．\n\nm が 0　のとき入力の終わりを示す. データセットの数は 5 を超えない．\n\n出力\n\n各データセットの出力は 1 行からなり， 2

If the specified width and\nheight of the estate are 4 and 3 respectively, the area surrounded by\nthe solid line contains the most persimmon trees. Similarly, if the\nestate's width is 6 and its height is 4, the area surrounded by the\ndashed line has the most, and if the estate's width and height are 3\nand 4 respectively, the area surrounded by the dotted line contains\nthe most persimmon trees. Note that the width and height cannot be\nswapped; the sizes 4 by 3 and 3 by 4 are different, as shown in Figure\n1.\n\nFigure 1: Examples of Rectangular Estates\n\nYour task is to find the estate of a given size (width and height)\nthat contains the largest number of persimmon trees.\n\nInput\n\nThe input consists of multiple data sets.\nEach data set is given in the following format.\n\nN\n\nW H\n\nx1 y1\n\nx2 y2\n\n...\n\nxN yN\n\nS T\n\nN is the number of persimmon trees,\nwhich is a positive integer less than 500.\nW and H are the width and the height of the entire field\nrespectively.\nYou can assume that both W and H are positive integers\nwhose values are less than 100.\nFor each i (1 <= i <= N),\nxi and yi are\ncoordinates of the i-th persimmon tree in the grid.\nNote that the origin of each coordinate is 1.\nYou can assume that 1 <= xi <= W\nand 1 <= yi <= H,\nand no two trees have the same positions.\nBut you should not assume that the persimmon trees are sorted in some order\naccording to their positions.\nLastly, S and T are positive integers of\nthe width and height respectively of the estate given by the lord.\nYou can also assume that 1 <= S <= W\nand 1 <= T <= H.\n\nThe end of the input is indicated by a line that solely contains a zero.\n\nOutput\n\nFor each data set, you are requested to print one line containing the\nmaximum possible number of persimmon trees that can be included in an\nestate of the given size.\n\nSample Input\n\n16\n10 8\n2 2\n2 5\n2 7\n3 3\n3 8\n4 2\n4 5\n4 8\n6 4\n6 7\n7 5\n7 8\n8 1\n8 4\n9 6\n10 3\n4 3\n8\n6 4\n1 2\n2 1\n2 4\n3 4\n4 2\n5 3\n6 1\n6 2\n3 2\n0\n\nOutput for the Sample Input\n\n4\n3", "split": "test_in_distribution", "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": 640, "cpu_time_ms": 3540, "memory_kb": 9084}, "variant": "medium_resource"}

The rooms are numbered 1 to N, and the passages are numbered 1 to M. Passage i connects Room A_i and Room B_i bidirectionally. One can travel between any two rooms by traversing passages. Room 1 is a special room with an entrance from the outside.\n\nIt is dark in the cave, so we have decided to place a signpost in each room except Room 1. The signpost in each room will point to one of the rooms directly connected to that room with a passage.\n\nSince it is dangerous in the cave, our objective is to satisfy the condition below for each room except Room 1.\n\nIf you start in that room and repeatedly move to the room indicated by the signpost in the room you are in, you will reach Room 1 after traversing the minimum number of passages possible.\n\nDetermine whether there is a way to place signposts satisfying our objective, and print one such way if it exists.\n\nConstraints\n\nAll values in input are integers.\n\n2 \\leq N \\leq 10^5\n\n1 \\leq M \\leq 2 \\times 10^5\n\n1 \\leq A_i, B_i \\leq N\\ (1 \\leq i \\leq M)\n\nA_i \\neq B_i\\ (1 \\leq i \\leq M)\n\nOne can travel between any two rooms by traversing passages.\n\nInput\n\nInput is given from Standard Input in the following format:\n\nN M\nA_1 B_1\n:\nA_M B_M\n\nOutput\n\nIf there is no way to place signposts satisfying the objective, print No.\n\nOtherwise, print N lines. The first line should contain Yes, and the i-th line (2 \\leq i \\leq N) should contain the integer representing the room indicated by the signpost in Room i.\n\nSample Input 1\n\n4 4\n1 2\n2 3\n3 4\n4 2\n\nSample Output 1\n\nYes\n1\n2\n2\n\nIf we place the signposts as described in the sample output, the following happens:\n\nStarting in Room 2, you will reach Room 1 after traversing one passage: (2) \\to 1. This is the minimum number of passages possible.\n\nStarting in Room 3, you will reach Room 1 after traversing two passages: (3) \\to 2 \\to 1.

The signpost in each room will point to one of the rooms directly connected to that room with a passage.\n\nSince it is dangerous in the cave, our objective is to satisfy the condition below for each room except Room 1.\n\nIf you start in that room and repeatedly move to the room indicated by the signpost in the room you are in, you will reach Room 1 after traversing the minimum number of passages possible.\n\nDetermine whether there is a way to place signposts satisfying our objective, and print one such way if it exists.\n\nConstraints\n\nAll values in input are integers.\n\n2 \\leq N \\leq 10^5\n\n1 \\leq M \\leq 2 \\times 10^5\n\n1 \\leq A_i, B_i \\leq N\\ (1 \\leq i \\leq M)\n\nA_i \\neq B_i\\ (1 \\leq i \\leq M)\n\nOne can travel between any two rooms by traversing passages.\n\nInput\n\nInput is given from Standard Input in the following format:\n\nN M\nA_1 B_1\n:\nA_M B_M\n\nOutput\n\nIf there is no way to place signposts satisfying the objective, print No.\n\nOtherwise, print N lines. The first line should contain Yes, and the i-th line (2 \\leq i \\leq N) should contain the integer representing the room indicated by the signpost in Room i.\n\nSample Input 1\n\n4 4\n1 2\n2 3\n3 4\n4 2\n\nSample Output 1\n\nYes\n1\n2\n2\n\nIf we place the signposts as described in the sample output, the following happens:\n\nStarting in Room 2, you will reach Room 1 after traversing one passage: (2) \\to 1. This is the minimum number of passages possible.\n\nStarting in Room 3, you will reach Room 1 after traversing two passages: (3) \\to 2 \\to 1. This is the minimum number of passages possible.\n\nStarting in Room 4, you will reach Room 1 after traversing two passages: (4) \\to 2 \\to 1.

Programming Contest is a programming contest voluntarily held by some Kyoto University students.\nThis contest is abbreviated as Kyoto University Programming Contest and called KUPC.\n\nsource: Kyoto University Programming Contest Information\n\nThe problem-preparing committee met to hold this year's KUPC and N problems were proposed there.\nThe problems are numbered from 1 to N and the name of i-th problem is P_i.\nHowever, since they proposed too many problems, they decided to divide them into some sets for several contests.\n\nThey decided to divide this year's KUPC into several KUPCs by dividing problems under the following conditions.\n\nOne KUPC provides K problems.\n\nEach problem appears at most once among all the KUPCs.\n\nAll the first letters of the problem names in one KUPC must be different.\n\nYou, one of the committee members, want to hold as many KUPCs as possible.\nWrite a program to find the maximum number of KUPCs that can be held this year.\n\nConstraints\n\n1 \\leq N \\leq 10^4\n\n1 \\leq K \\leq 26\n\n1 \\leq |P_i| \\leq 10\n\nAll characters in P_i are capital letters.\n\nNote that, for each i and j (1 \\leq i < j \\leq N),\nP_i \\neq P_j are not necessarily satisfied.\n\nInput\n\nThe input is given from Standard Input in the following format:\n\nN K\nP_1\n:\nP_N\n\nOutput\n\nPrint the maximum number of KUPCs that can be held on one
