Then you can recursively call the following functions:\n\nsolve(0, M)\n\nsolve(1, M-{sum created from elements before 1st element})\n\nsolve(2, M-{sum created from elements before 2nd element})\n\n...\n\nThe recursive function has two choices: you selected p-th element and not. So, you can check solve(p+1, t-A[p]) and solve(p+1, t) in solve(p, t) to check the all combinations.\n\nFor example, the following figure shows that 8 can be made by A[0] + A[2].", "split": "train", "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": 2327, "cpu_time_ms": 410, "memory_kb": 128596}, "variant": "low_resource"} {"dataset": "codeNet", "domain": "code_generation", "example_id": "codeNet:OCaml:s552159015", "group_id": "codeNet:p02272", "input_text": "let to_array s =\n Str.split (Str.regexp_string \" \") s\n |> List.map int_of_string\n |> Array.of_list;;\n\nlet print_array l =\n Array.map string_of_int l\n |> Array.to_list\n |> String.concat \" \"\n |> print_endline;;\n\nlet merge (a:int array) left mid right =\n let n1 = mid - left and\n n2 = right - mid in\n let l = Array.init (n1+1) (fun i -> if i < n1 then a.(left+i) else max_int) and\n r = Array.init (n2+1) (fun i -> if i < n2 then a.(mid+i) else max_int) and\n i = ref 0 and\n j = ref 0 and\n count = ref 0\n in\n for k = left to right-1 do\n if l.(!i) <= r.(!j) then\n begin\n a.(k) <- l.(!i); i := !i+1\n end\n else\n begin\n a.(k) <- r.(!j); j := !j+1\n end;\n count := !count+1\n done;\n !count\n\nlet rec merge_sort a left right count =\n if left + 1 < right then\n let mid = (left+right)/2 in\n let count1 = merge_sort a left mid count and\n count2 = merge_sort a mid right count in\n count1 + count2 + (merge a left mid right)\n else count\n;;\n\nlet () =\n let _ = read_int () and\n a = read_line () |> to_array in\n let count = merge_sort a 0 (Array.length a) 0 in\n print_array a;\n print_int count;\n print_newline ()\n;;", "language": "OCaml", "metadata": {"date": 1468334057, "filename_ext": "ml", "original_language": "OCaml", "problem_description_relpath": "problem_descriptions/p02272.html", "problem_id": "p02272", "resource_group": "low_resource", "sample_input_relpath": "derived/input_output/data/p02272/input.txt", "sample_output_relpath": "derived/input_output/data/p02272/output.txt", "source_dataset": "Project CodeNet", "source_relpath": "data/p02272/OCaml/s552159015.ml", "split_policy": "Global OOD problem IDs are disjoint from train, validation, and in-distribution test problem IDs.", "status": "Accepted", "submission_id": "s552159015", "user_id": "u935184340"}, "prompt_components": {"gold_output": "1 2 3 4 5 6 7 8 9 10\n34\n", "input_to_evaluate": "let to_array s =\n Str.split (Str.regexp_string \" \") s\n |> List.map int_of_string\n |> Array.of_list;;\n\nlet print_array l =\n Array.map string_of_int l\n |> Array.to_list\n |> String.concat \" \"\n |> print_endline;;\n\nlet merge (a:int array) left mid right =\n let n1 = mid - left and\n n2 = right - mid in\n let l = Array.init (n1+1) (fun i -> if i < n1 then a.(left+i) else max_int) and\n r = Array.init (n2+1) (fun i -> if i < n2 then a.(mid+i) else max_int) and\n i = ref 0 and\n j = ref 0 and\n count = ref 0\n in\n for k = left to right-1 do\n if l.(!i) <= r.(!j) then\n begin\n a.(k) <- l.(!i); i := !i+1\n end\n else\n begin\n a.(k) <- r.(!j); j := !j+1\n end;\n count := !count+1\n done;\n !count\n\nlet rec merge_sort a left right count =\n if left + 1 < right then\n let mid = (left+right)/2 in\n let count1 = merge_sort a left mid count and\n count2 = merge_sort a mid right count in\n count1 + count2 + (merge a left mid right)\n else count\n;;\n\nlet () =\n let _ = read_int () and\n a = read_line () |> to_array in\n let count = merge_sort a 0 (Array.length a) 0 in\n print_array a;\n print_int count;\n print_newline ()\n;;", "problem_context": "Merge Sort\n\nWrite a program of a Merge Sort algorithm implemented by the following pseudocode.

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. This is the minimum number of passages possible.\n\nThus, the objective is satisfied.\n\nSample Input 2\n\n6 9\n3 4\n6 1\n2 4\n5 3\n4 6\n1 5\n6 2\n4 5\n5 6\n\nSample Output 2\n\nYes\n6\n5\n5\n1\n1\n\nIf there are multiple solutions, any of them will be accepted.", "split": "train", "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": 6545, "cpu_time_ms": 193, "memory_kb": 32872}, "variant": "low_resource"} {"dataset": "codeNet", "domain": "code_generation", "example_id": "codeNet:OCaml:s137077099", "group_id": "codeNet:p02679", "input_text": "open Batteries\nmodule EnumL = Enum.Labels\nmodule ListL = List.Labels\nmodule ArrayL = Array.Labels\n\nlet dbg0 x = Printf.eprintf \"[debug]%s\\n\" @@ dump x\nlet dbg1 x = dbg0 x;

The number resulted will be the number of contestants advancing to the next round.\n\nFor example, when X = 2378, the number of contestants advancing to the next round will be 578 (if 2 and 3 are chosen), 2108 (if 3 and 7 are chosen), or 2315 (if 7 and 8 are chosen).\n\nWhen X = 100, the number of contestants advancing to the next round will be 10, no matter which two digits are chosen.\n\nThe preliminary stage ends when 9 or fewer contestants remain.\n\nRingo, the chief organizer, wants to hold as many rounds as possible.\nFind the maximum possible number of rounds in the preliminary stage.\n\nSince the number of contestants, N, can be enormous, it is given to you as two integer sequences d_1, \\ldots, d_M and c_1, \\ldots, c_M, which means the following: the decimal notation of N consists of c_1 + c_2 + \\ldots + c_M digits, whose first c_1 digits are all d_1, the following c_2 digits are all d_2, \\ldots, and the last c_M digits are all d_M.\n\nConstraints\n\n1 \\leq M \\leq 200000\n\n0 \\leq d_i \\leq 9\n\nd_1 \\neq 0\n\nd_i \\neq d_{i+1}\n\nc_i \\geq 1\n\n2 \\leq c_1 + \\ldots + c_M \\leq 10^{15}\n\nInput\n\nInput is given from Standard Input in the following format:\n\nM\nd_1 c_1\nd_2 c_2\n:\nd_M c_M\n\nOutput\n\nPrint the maximum possible number of rounds in the preliminary stage.\n\nSample Input 1\n\n2\n2 2\n9 1\n\nSample Output 1\n\n3\n\nIn this case, N = 229 contestants will participate in the first round.

factory:\n\nThe robot arm consists of m sections and m+1 joints. The sections are numbered 1, 2, ..., m, and the joints are numbered 0, 1, ..., m. Section i connects Joint i-1 and Joint i. The length of Section i is d_i.\n\nFor each section, its mode can be specified individually. There are four modes: L, R, D and U. The mode of a section decides the direction of that section. If we consider the factory as a coordinate plane, the position of Joint i will be determined as follows (we denote its coordinates as (x_i, y_i)):\n\n(x_0, y_0) = (0, 0).\n\nIf the mode of Section i is L, (x_{i}, y_{i}) = (x_{i-1} - d_{i}, y_{i-1}).\n\nIf the mode of Section i is R, (x_{i}, y_{i}) = (x_{i-1} + d_{i}, y_{i-1}).\n\nIf the mode of Section i is D, (x_{i}, y_{i}) = (x_{i-1}, y_{i-1} - d_{i}).\n\nIf the mode of Section i is U, (x_{i}, y_{i}) = (x_{i-1}, y_{i-1} + d_{i}).\n\nSnuke would like to introduce a robot arm so that the position of Joint m can be matched with all of the N points (X_1, Y_1), (X_2, Y_2), ..., (X_N, Y_N) by properly specifying the modes of the sections.\nIs this possible?\nIf so, find such a robot arm and how to bring Joint m to each point (X_j, Y_j).\n\nConstraints\n\nAll values in input are integers.\n\n1 \\leq N \\leq 1000\n\n-10^9 \\leq X_i \\leq 10^9\n\n-10^9 \\leq Y_i \\leq 10^9\n\nPartial Score\n\nIn the test cases worth 300 points, -10 \\leq X_i \\leq 10 and -10 \\leq Y_i \\leq 10 hold.\n\nInput\n\nInput is given from Standard Input in the following format:\n\nN\nX_1 Y_1\nX_2 Y_2\n:\nX_N Y_N\n\nOutput\n\nIf the condition can be satisfied, follow the following format.

The sections are numbered 1, 2, ..., m, and the joints are numbered 0, 1, ..., m. Section i connects Joint i-1 and Joint i. The length of Section i is d_i.\n\nFor each section, its mode can be specified individually. There are four modes: L, R, D and U. The mode of a section decides the direction of that section. If we consider the factory as a coordinate plane, the position of Joint i will be determined as follows (we denote its coordinates as (x_i, y_i)):\n\n(x_0, y_0) = (0, 0).\n\nIf the mode of Section i is L, (x_{i}, y_{i}) = (x_{i-1} - d_{i}, y_{i-1}).\n\nIf the mode of Section i is R, (x_{i}, y_{i}) = (x_{i-1} + d_{i}, y_{i-1}).\n\nIf the mode of Section i is D, (x_{i}, y_{i}) = (x_{i-1}, y_{i-1} - d_{i}).\n\nIf the mode of Section i is U, (x_{i}, y_{i}) = (x_{i-1}, y_{i-1} + d_{i}).\n\nSnuke would like to introduce a robot arm so that the position of Joint m can be matched with all of the N points (X_1, Y_1), (X_2, Y_2), ..., (X_N, Y_N) by properly specifying the modes of the sections.\nIs this possible?\nIf so, find such a robot arm and how to bring Joint m to each point (X_j, Y_j).\n\nConstraints\n\nAll values in input are integers.\n\n1 \\leq N \\leq 1000\n\n-10^9 \\leq X_i \\leq 10^9\n\n-10^9 \\leq Y_i \\leq 10^9\n\nPartial Score\n\nIn the test cases worth 300 points, -10 \\leq X_i \\leq 10 and -10 \\leq Y_i \\leq 10 hold.\n\nInput\n\nInput is given from Standard Input in the following format:\n\nN\nX_1 Y_1\nX_2 Y_2\n:\nX_N Y_N\n\nOutput\n\nIf the condition can be satisfied, follow the following format.

If we consider the factory as a coordinate plane, the position of Joint i will be determined as follows (we denote its coordinates as (x_i, y_i)):\n\n(x_0, y_0) = (0, 0).\n\nIf the mode of Section i is L, (x_{i}, y_{i}) = (x_{i-1} - d_{i}, y_{i-1}).\n\nIf the mode of Section i is R, (x_{i}, y_{i}) = (x_{i-1} + d_{i}, y_{i-1}).\n\nIf the mode of Section i is D, (x_{i}, y_{i}) = (x_{i-1}, y_{i-1} - d_{i}).\n\nIf the mode of Section i is U, (x_{i}, y_{i}) = (x_{i-1}, y_{i-1} + d_{i}).\n\nSnuke would like to introduce a robot arm so that the position of Joint m can be matched with all of the N points (X_1, Y_1), (X_2, Y_2), ..., (X_N, Y_N) by properly specifying the modes of the sections.\nIs this possible?\nIf so, find such a robot arm and how to bring Joint m to each point (X_j, Y_j).\n\nConstraints\n\nAll values in input are integers.\n\n1 \\leq N \\leq 1000\n\n-10^9 \\leq X_i \\leq 10^9\n\n-10^9 \\leq Y_i \\leq 10^9\n\nPartial Score\n\nIn the test cases worth 300 points, -10 \\leq X_i \\leq 10 and -10 \\leq Y_i \\leq 10 hold.\n\nInput\n\nInput is given from Standard Input in the following format:\n\nN\nX_1 Y_1\nX_2 Y_2\n:\nX_N Y_N\n\nOutput\n\nIf the condition can be satisfied, follow the following format. If the condition cannot be satisfied, print -1.\n\nm\nd_1 d_2 ... d_m\nw_1\nw_2\n:\nw_N\n\nm and d_i are the configurations of the robot arm. Refer to the problem statement for what each of them means.\nHere, 1 \\leq m \\leq 40 and 1 \\leq d_i \\leq 10^{12} must hold. Also, m and d_i must all be integers.\n\nw_j is a string of length m that represents the way to bring Joint m of the robot arm to point (X_j, Y_j).\nThe i-th character of w_j should be one of the letters L, R, D and U, representing the mode of Section i.\n\nSample Input 1\n\n3\n-1 0\n0 3\n2 -1\n\nSample Output 1\n\n2\n1 2\nRL\nUU\nDR\n\nIn the given way to bring Joint m of the robot arm to each (X_j, Y_j), the positions of the joints will be as follows:\n\nTo (X_1, Y_1) = (-1, 0): First, the position of Joint 0 is (x_0, y_0) = (0, 0). As the mode of Section 1 is R, the position of Joint 1 is (x_1, y_1) = (1, 0). Then, as the mode of Section 2 is L, the position of Joint 2 is (x_2, y_2) = (-1, 0).\n\nTo (X_2, Y_2) = (0, 3): (x_0, y_0) = (0, 0), (x_1, y_1) = (0, 1), (x_2, y_2) = (0, 3).\n\nTo (X_3, Y_3) = (2, -1): (x_0, y_0) = (0, 0), (x_1, y_1) = (0, -1), (x_2, y_2) = (2, -1).\n\nSample Input 2\n\n5\n0 0\n1 0\n2 0\n3 0\n4 0\n\nSample Output 2\n\n-1\n\nSample Input 3\n\n2\n1 1\n1 1\n\nSample Output 3\n\n2\n1 1\nRU\nUR\n\nThere may be duplicated points among (X_j, Y_j).\n\nSample Input 4\n\n3\n-7 -3\n7 3\n-3 -7\n\nSample Output 4\n\n5\n3 1 4 1 5\nLRDUL\nRDULR\nDULRD", "split": "train", "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": 6185, "cpu_time_ms": 5, "memory_kb": 4736}, "variant": "low_resource"} {"dataset": "codeNet", "domain": "code_generation", "example_id": "codeNet:OCaml:s634352600", "group_id": "codeNet:p03248", "input_text": "Scanf.scanf \"%s\" (fun s ->\n let n = String.length s in\n let proc () =\n let rec loop i prev acc =\n if i = n - 1 then prev, acc else \n let acc = (prev, i + 2) :: acc in\n if i >= n / 2 then loop (i + 1) prev acc else\n if s.[i] <> s.[n - 2 - i] then prev, [] else\n if s.[i] = '1' then loop (i + 1) (i + 2) acc\n else loop (i + 1) prev acc\n in\n let prev, acc = loop 0 1 [] in\n if acc = [] then print_endline \"-1\" else\n List.iter (fun (a, b) -> Printf.printf \"%d %d\\n\" a b) acc\n in\n if s.[n - 1] = '1' || s.[0] = '0' || s.[n - 2] = '0' then print_endline \"-1\" else proc ()\n)", "language": "OCaml", "metadata": {"date": 1599547190, "filename_ext": "ml", "original_language": "OCaml (4.10.0)", "problem_description_relpath": "problem_descriptions/p03248.html", "problem_id": "p03248", "resource_group": "low_resource", "sample_input_relpath": "derived/input_output/data/p03248/input.txt", "sample_output_relpath": "derived/input_output/data/p03248/output.txt", "source_dataset": "Project CodeNet", "source_relpath": "data/p03248/OCaml/s634352600.ml", "split_policy": "Global OOD problem IDs are disjoint from train, validation, and in-distribution test problem IDs.", "status": "Accepted", "submission_id": "s634352600", "user_id": "u342443598"}, "prompt_components": {"gold_output": "-1\n", "input_to_evaluate": "Scanf.scanf \"%s\" (fun s ->\n let n = String.length s in\n let proc () =\n let rec loop i prev acc =\n if i = n - 1 then prev, acc else \n let acc = (prev, i + 2) :: acc in\n if i >= n / 2 then loop (i + 1) prev acc else\n if s.[i] <> s.[n - 2 - i] then prev, [] else\n if s.[i] = '1' then loop (i + 1) (i + 2) acc\n else loop (i + 1) prev acc\n in\n let prev, acc = loop 0 1 [] in\n if acc = [] then print_endline \"-1\" else\n List.iter (fun (a, b) -> Printf.printf \"%d %d\\n\" a b) acc\n in\n if s.[n - 1] = '1' || s.[0] = '0' || s.[n - 2] = '0' then print_endline \"-1\" else proc ()\n)", "problem_context": "Score : 700 points\n\nProblem Statement\n\nYou are given a string s of length n.\nDoes a tree with n vertices that satisfies the following conditions exist?\n\nThe vertices are numbered 1,2,..., n.\n\nThe edges are numbered 1,2,..., n-1, and Edge i connects Vertex u_i and v_i.\n\nIf the i-th character in s is 1, we can have a connected component of size i by removing one edge from the tree.\n\nIf the i-th character in s is 0, we cannot have a connected component of size i by removing any one edge from the tree.\n\nIf such a tree exists, construct one such tree.\n\nConstraints\n\n2 \\leq n \\leq 10^5\n\ns is a string of length n consisting of 0 and 1.\n\nInput\n\nInput is given from Standard Input in the following format:\n\ns\n\nOutput\n\nIf a tree with n vertices that satisfies the conditions does not exist, print -1.\n\nIf a tree with n vertices that satisfies the conditions exist, print n-1 lines.\nThe i-th line should contain u_i and v_i with a space in between.\nIf there are multiple trees that satisfy the conditions, any such tree will be accepted.\n\nSample Input 1\n\n1111\n\nSample Output 1\n\n-1\n\nIt is impossible to have a connected component of size n after removing one edge from a tree with n vertices.\n\nSample Input 2\n\n1110\n\nSample Output 2\n\n1 2\n2 3\n3 4\n\nIf Edge 1 or Edge 3 is removed, we will have a connected component of size 1 and another of size 3.
