Please see the following pseudocode for the detail:\n\nCounting-Sort(A, B, k)\n1 for i = 0 to k\n2 do C[i] = 0\n3 for j = 1 to length[A]\n4 do C[A[j]] = C[A[j]]+1\n5 /* C[i] now contains the number of elements equal to i */\n6 for i = 1 to k\n7 do C[i] = C[i] + C[i-1]\n8 /* C[i] now contains the number of elements less than or equal to i */\n9 for j = length[A] downto 1\n10 do B[C[A[j]]] = A[j]\n11 C[A[j]] = C[A[j]]-1\n\nWrite a program which sorts elements of given array ascending order based on the counting sort.\n\nInput\n\nThe first line of the input includes an integer n, the number of elements in the sequence.\n\nIn the second line, n elements of the sequence are given separated by spaces characters.\n\nOutput\n\nPrint the sorted sequence.

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. In the following $m$ lines, operations represented by insert $k$ or print are given.\n\nOutput\n\nFor each print operation, print a list of keys obtained by inorder tree walk and preorder tree walk in a line respectively.

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.

Nevertheless, writing a score calculator by yourself is still useful to check your understanding of the problem specification. Moreover, the source code of the score calculator can often be reused for solving the problem or debugging your solution.

It does not satisfy the constraint D=365 and is never actually given as a test case.\n\nNext Step\n\nWe can build a solution (schedule) for this problem in the order of day 1, day 2, and so on. And for every partial solution we have built, we can calculate the goodness (satisfaction) by using the above score calculator. So we can construct the following algorithm: for each d=1,2,\\ldots,D, we select the contest type that maximizes the satisfaction at the end of day d. You may have already encountered this kind of \"greedy algorithms\" in algorithm contests such as ABC. Greedy algorithms can guarantee the optimality for several problems, but unfortunately, it doesn't ensure optimality for this problem. However, even if it does not ensure optimality, we can still obtain a reasonable solution in many cases. Let's go back to Problem A and implement the greedy algorithm by utilizing the score calculator you just implemented!\n\nGreedy methods can be applied to a variety of problems, are easy to implement, and often run relatively fast compared to other methods. Greedy is often the most powerful method when we need to process huge inputs.\nWe can further improve the score by changing the greedy selection criteria (evaluation function), keeping multiple candidates instead of focusing on one best partial solution (beam search), or using the output of greedy algorithms as an initial solution of other methods.\nFor more information, please refer to the editorial that will be published after the contest.", "sample_input": "5\n86 90 69 51 2 96 71 47 88 34 45 46 89 34 31 38 97 84 41 80 14 4 50 83 7 82\n19771 12979 18912 10432 10544 12928 13403 3047 10527 9740 8100 92 2856 14730 1396 15905 6534 4650 11469 3628 8433 2994 10899 16396 18355 11424\n6674 17707 13855 16407 12232 2886 11908 1705 5000 1537 10440 10711 4917 10770 17272 15364 19277 18094 3929 3705 7169 6159 18683 15410 9092 4570\n6878 4239 19925 1799 375 9563 3445 5658 19857 11401 6997 6498 19933 3848 2426 2146 19745 16880 17773 18359 3921 14172 16730 11157 5439 256\n8633 15862 15303 10749 18499 7792 10317 5901 9395 11433 3514 3959 5202 19850 19469 9790 5653 784 18500 10552 17975 16615 7852 197 8471 7452\n19855 17918 7990 10572 4333 438 9140 9104 12622 4985 12319 4028 19922 12132 16259 17476 2976 547 19195 19830 16285 4806 4471 9457 2864 2192\n1\n17\n13\n14\n13\n"}, "reference_outputs": ["18398\n35037\n51140\n65837\n79325\n"], "source_document_id": "p02619", "source_text": "(Please read problem A first.

So it is worthwhile to write a score calculator unless it is very complicated.\n\nProblem Statement\n\nYou will be given a contest schedule for D days.\nFor each d=1,2,\\ldots,D, calculate the satisfaction at the end of day d.\n\nInput\n\nInput is given from Standard Input in the form of the input of Problem A followed by the output of Problem A.\n\nD\nc_1 c_2 \\cdots c_{26}\ns_{1,1} s_{1,2} \\cdots s_{1,26}\n\\vdots\ns_{D,1} s_{D,2} \\cdots s_{D,26}\nt_1\nt_2\n\\vdots\nt_D\n\nThe constraints and generation methods for the input part are the same as those for Problem A.\n\nFor each d, t_d is an integer satisfying 1\\leq t_d \\leq 26, and your program is expected to work correctly for any value that meets the constraints.\n\nOutput\n\nLet v_d be the satisfaction at the end of day d.\nPrint D integers v_d to Standard Output in the following format:\n\nv_1\nv_2\n\\vdots\nv_D\n\nSample Input 1\n\n5\n86 90 69 51 2 96 71 47 88 34 45 46 89 34 31 38 97 84 41 80 14 4 50 83 7 82\n19771 12979 18912 10432 10544 12928 13403 3047 10527 9740 8100 92 2856 14730 1396 15905 6534 4650 11469 3628 8433 2994 10899 16396 18355 11424\n6674 17707 13855 16407 12232 2886 11908 1705 5000 1537 10440 10711 4917 10770 17272 15364 19277 18094 3929 3705 7169 6159 18683 15410 9092 4570\n6878 4239 19925 1799 375 9563 3445 5658 19857 11401 6997 6498 19933 3848 2426 2146 19745 16880 17773 18359 3921 14172 16730 11157 5439 256\n8633 15862 15303 10749 18499 7792 10317 5901 9395 11433 3514 3959 5202 19850 19469 9790 5653 784 18500 10552 17975 16615 7852 197 8471 7452\n19855 17918 7990 10572 4333 438 9140 9104 12622 4985 12319 4028 19922 12132 16259 17476 2976 547 19195 19830 16285 4806 4471 9457 2864 2192\n1\n17\n13\n14\n13\n\nSample Output 1\n\n18398\n35037\n51140\n65837\n79325\n\nNote that this example is a small one for checking the problem specification. It does not satisfy the constraint D=365 and is never actually given as a test case.\n\nNext Step\n\nWe can build a solution (schedule) for this problem in the order of day 1, day 2, and so on. And for every partial solution we have built, we can calculate the goodness (satisfaction) by using the above score calculator. So we can construct the following algorithm: for each d=1,2,\\ldots,D, we select the contest type that maximizes the satisfaction at the end of day d. You may have already encountered this kind of \"greedy algorithms\" in algorithm contests such as ABC. Greedy algorithms can guarantee the optimality for several problems, but unfortunately, it doesn't ensure optimality for this problem. However, even if it does not ensure optimality, we can still obtain a reasonable solution in many cases. Let's go back to Problem A and implement the greedy algorithm by utilizing the score calculator you just implemented!\n\nGreedy methods can be applied to a variety of problems, are easy to implement, and often run relatively fast compared to other methods. Greedy is often the most powerful method when we need to process huge inputs.\nWe can further improve the score by changing the greedy selection criteria (evaluation function), keeping multiple candidates instead of focusing on one best partial solution (beam search), or using the output of greedy algorithms as an initial solution of other methods.\nFor more information, please refer to the editorial that will be published after the contest.", "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": 743, "cpu_time_ms": 13, "memory_kb": 5916}, "variant": "low_resource"} {"dataset": "codeNet", "domain": "code_generation", "example_id": "codeNet:OCaml:s622084974", "group_id": "codeNet:p02621", "input_text": "open Scanf\nopen Printf\n\nlet a = scanf \"%d\" (fun a -> a)\nlet () = printf \"%d\\n\" (a + a * a + a * a * a)\n", "language": "OCaml", "metadata": {"date": 1593306074, "filename_ext": "ml", "original_language": "OCaml (4.10.0)", "problem_description_relpath": "problem_descriptions/p02621.html", "problem_id": "p02621", "resource_group": "low_resource", "sample_input_relpath": "derived/input_output/data/p02621/input.txt", "sample_output_relpath": "derived/input_output/data/p02621/output.txt", "source_dataset": "Project CodeNet", "source_relpath": "data/p02621/OCaml/s622084974.ml", "split_policy": "Global OOD problem IDs are disjoint from train, validation, and in-distribution test problem IDs.", "status": "Accepted", "submission_id": "s622084974", "user_id": "u809832909"}, "prompt_components": {"gold_output": "14\n", "input_to_evaluate": "open Scanf\nopen Printf\n\nlet a = scanf \"%d\" (fun a -> a)\nlet () = printf \"%d\\n\" (a + a * a + a * a * a)\n", "problem_context": "Score : 100 points\n\nProblem Statement\n\nGiven an integer a as input, print the value a + a^2 + a^3.\n\nConstraints\n\n1 \\leq a \\leq 10\n\na is an integer.\n\nInput\n\nInput is given from Standard Input in the following format:\n\na\n\nOutput\n\nPrint the value a + a^2 + a^3 as an integer.\n\nSample Input 1\n\n2\n\nSample Output 1\n\n14\n\nWhen a = 2, we have a + a^2 + a^3 = 2 + 2^2 + 2^3 = 2 + 4 + 8 = 14.\n\nPrint the answer as an input.

In one explosion, you can damage monsters as follows:\n\nSelect an alive monster, and cause an explosion centered at that monster. The health of the monster at the center of the explosion will decrease by A, and the health of each of the other monsters will decrease by B. Here, A and B are predetermined parameters, and A > B holds.\n\nAt least how many explosions do you need to cause in order to vanish all the monsters?\n\nConstraints\n\nAll input values are integers.\n\n1 ≤ N ≤ 10^5\n\n1 ≤ B < A ≤ 10^9\n\n1 ≤ h_i ≤ 10^9\n\nInput\n\nInput is given from Standard Input in the following format:\n\nN A B\nh_1\nh_2\n:\nh_N\n\nOutput\n\nPrint the minimum number of explosions that needs to be caused in order to vanish all the monsters.\n\nSample Input 1\n\n4 5 3\n8\n7\n4\n2\n\nSample Output 1\n\n2\n\nYou can vanish all the monsters in two explosion, as follows:\n\nFirst, cause an explosion centered at the monster with 8 health. The healths of the four monsters become 3, 4, 1 and -1, respectively, and the last monster vanishes.\n\nSecond, cause an explosion centered at the monster with 4 health remaining. The healths of the three remaining monsters become 0, -1 and -2, respectively, and all the monsters are now vanished.\n\nSample Input 2\n\n2 10 4\n20\n20\n\nSample Output 2\n\n4\n\nYou need to cause two explosions centered at each monster, for a total of four.\n\nSample Input 3\n\n5 2 1\n900000000\n900000000\n1000000000\n1000000000\n1000000000\n\nSample Output 3\n\n800000000", "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": 1152, "cpu_time_ms": 155, "memory_kb": 11648}, "variant": "low_resource"} {"dataset": "codeNet", "domain": "code_generation", "example_id": "codeNet:OCaml:s352096921", "group_id": "codeNet:p03711", "input_text": "let a = [1;3;5;7;8;10;12];;\nlet b = [4;6;9;11];;\nlet c = [2];;\n\nlet (x, y) = Scanf.scanf \"%d %d\" (fun x y -> (x, y));;\nlet ans =\n if List.mem x a && List.mem y a then\n \"Yes\"\n else if List.mem x b && List.mem y b then\n \"Yes\"\n else if List.mem x c && List.mem y c then\n \"Yes\"\n else\n \"No\";;\nlet () = print_endline ans;;\n", "language": "OCaml", "metadata": {"date": 1571857494, "filename_ext": "ml", "original_language": "OCaml (4.02.3)", "problem_description_relpath": "problem_descriptions/p03711.html", "problem_id": "p03711", "resource_group": "low_resource", "sample_input_relpath": "derived/input_output/data/p03711/input.txt", "sample_output_relpath": "derived/input_output/data/p03711/output.txt", "source_dataset": "Project CodeNet", "source_relpath": "data/p03711/OCaml/s352096921.ml", "split_policy": "Global OOD problem IDs are disjoint from train, validation, and in-distribution test problem IDs.", "status": "Accepted", "submission_id": "s352096921", "user_id": "u614063956"}, "prompt_components": {"gold_output": "Yes\n", "input_to_evaluate": "let a = [1;3;5;7;8;10;12];;\nlet b = [4;6;9;11];;\nlet c = [2];;\n\nlet (x, y) = Scanf.scanf \"%d %d\" (fun x y -> (x, y));;\nlet ans =\n if List.mem x a && List.mem y a then\n \"Yes\"\n else if List.mem x b && List.mem y b then\n \"Yes\"\n else if List.mem x c && List.mem y c then\n \"Yes\"\n else\n \"No\";;\nlet () = print_endline ans;;\n", "problem_context": "Score : 100 points\n\nProblem Statement\n\nBased on some criterion, Snuke divided the integers from 1 through 12 into three groups as shown in the figure below.\nGiven two integers x and y (1 ≤ x < y ≤ 12), determine whether they belong to the same group.\n\nConstraints\n\nx and y are integers.\n\n1 ≤ x < y ≤ 12\n\nInput\n\nInput is given from Standard Input in the following format:\n\nx y\n\nOutput\n\nIf x and y belong to the same group, print Yes;
