The maximum score you can get by solving this problem B is 1, which will have almost no effect on your ranking.)\n\nBeginner's Guide\n\nLet's first write a program to calculate the score from a pair of input and output. You can know the total score by submitting your solution, or an official program to calculate a score is often provided for local evaluation as in this contest. 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. 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.

The maximum score you can get by solving this problem B is 1, which will have almost no effect on your ranking.)\n\nBeginner's Guide\n\nLet's first write a program to calculate the score from a pair of input and output. You can know the total score by submitting your solution, or an official program to calculate a score is often provided for local evaluation as in this contest. 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. 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.

The maximum score you can get by solving this problem C is 1, which will have almost no effect on your ranking.)\n\nBeginner's Guide\n\n\"Local search\" is a powerful method for finding a high-quality solution.\nIn this method, instead of constructing a solution from scratch, we try to find a better solution by slightly modifying the already found solution.\nIf the solution gets better, update it, and if it gets worse, restore it.\nBy repeating this process, the quality of the solution is gradually improved over time.\nThe pseudo-code is as follows.\n\nsolution = compute an initial solution (by random generation, or by applying other methods such as greedy)\nwhile the remaining time > 0:\nslightly modify the solution (randomly)\nif the solution gets worse:\nrestore the solution\n\nFor example, in this problem, we can use the following modification: pick the date d and contest type q at random and change the type of contest to be held on day d to q.\nThe pseudo-code is as follows.\n\nt[1..D] = compute an initial solution (by random generation, or by applying other methods such as greedy)\nwhile the remaining time > 0:\npick d and q at random\nold = t[d] # Remember the original value so that we can restore it later\nt[d] = q\nif the solution gets worse:\nt[d] = old\n\nThe most important thing when using the local search method is the design of how to modify solutions.\n\nIf the amount of modification is too small, we will soon fall into a dead-end (local optimum) and, conversely, if the amount of modification is too large, the probability of finding an improving move becomes extremely small.\n\nIn order to increase the number of iterations, it is desirable to be able to quickly calculate the score after applying a modification.\n\nIn this problem C, we focus on the second point.\nThe score after the modification can, of course, be obtained by calculating the score from scratch.\nHowever, by focusing on only the parts that have been modified, it may be possible to quickly compute the difference between the scores before and after the modification.\nFrom another viewpoint, the impossibility of such a fast incremental calculation implies that a small modification to the solution affects a majority of the score calculation.\nIn such a case, we may need to redesign how to modify solutions, or there is a high possibility that the problem is not suitable for local search.\nLet's implement fast incremental score computation.\nIt's time to demonstrate the skills of algorithms and data structures you have developed in ABC and ARC!\n\nIn this kind of contest, where the objective is to find a better solution instead of the optimal one, a bug in a program does not result in a wrong answer, which may delay the discovery of the bug.\nFor early detection of bugs, it is a good idea to unit test functions you implemented complicated routines.\nFor example, if you implement fast incremental score calculation, it is a good idea to test that the scores computed by the fast implementation match the scores computed from scratch, as we will do in this problem C.\n\nProblem Statement\n\nYou will be given a contest schedule for D days and M queries of schedule modification.\nIn the i-th query, given integers d_i and q_i, change the type of contest to be held on day d_i to q_i, and then output the final satisfaction at the end of day D on the updated schedule.\nNote that we do not revert each query. That is, the i-th query is applied to the new schedule obtained by the (i-1)-th query.\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 and the queries.\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\nM\nd_1 q_1\nd_2 q_2\n\\vdots\nd_M q_M\n\nThe constraints and generation methods for the input part are the same as those for Problem A.\n\nFor each d=1,\\ldots,D, t_d is an integer generated independently and uniformly at random from {1,2,\\ldots,26}.\n\nThe number of queries M is an integer satisfying 1\\leq M\\leq 10^5.\n\nFor each i=1,\\ldots,M, d_i is an integer generated independently and uniformly at random from {1,2,\\ldots,D}.\n\nFor each i=1,\\ldots,26, q_i is an integer satisfying 1\\leq q_i\\leq 26 generated uniformly at random from the 25 values that differ from the type of contest on day d_i.\n\nOutput\n\nLet v_i be the final satisfaction at the end of day D on the schedule after applying the i-th query.\nPrint M integers v_i to Standard Output in the following format:\n\nv_1\nv_2\n\\vdots\nv_M\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\n5\n1 7\n4 11\n3 4\n5 24\n4 19\n\nSample Output 1\n\n72882\n56634\n38425\n27930\n42884\n\nNote that this example is a small one for checking the problem specification.

It is not possible to circle both s_3 and s_4 at the same time, either.\n\nFind the maximum number of integers that Snuke can circle.\n\nConstraints\n\n1 ≦ N ≦ 10^5\n\n1 ≦ s_i ≦ 10^{10}\n\nAll input values are integers.\n\nInput\n\nThe input is given from Standard Input in the following format:\n\nN\ns_1\n:\ns_N\n\nOutput\n\nPrint the maximum number of integers that Snuke can circle.\n\nSample Input 1\n\n8\n1\n2\n3\n4\n5\n6\n7\n8\n\nSample Output 1\n\n6\n\nSnuke can circle 1,2,3,5,6,7.\n\nSample Input 2\n\n6\n2\n4\n8\n16\n32\n64\n\nSample Output 2\n\n3\n\nSample Input 3\n\n10\n1\n10\n100\n1000000007\n10000000000\n1000000009\n999999999\n999\n999\n999\n\nSample Output 3\n\n9", "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": 14058, "cpu_time_ms": 2367, "memory_kb": 83168}, "variant": "low_resource"} {"dataset": "codeNet", "domain": "code_generation", "example_id": "codeNet:Lisp:s423341852", "group_id": "codeNet:p04022", "input_text": "(eval-when (:compile-toplevel :load-toplevel :execute)\n (sb-int:defconstant-eqx OPT\n #+swank '(optimize (speed 3) (safety 2))\n #-swank '(optimize (speed 3) (safety 0) (debug 0))\n #'equal)\n #+swank (ql:quickload '(:cl-debug-print :fiveam) :silent t)\n #-swank (set-dispatch-macro-character\n ;; enclose the form with VALUES to avoid being captured by LOOP macro\n #\\# #\\> (lambda (s c p) (declare (ignore c p)) `(values ,(read s nil nil t)))))\n#+swank (cl-syntax:use-syntax cl-debug-print:debug-print-syntax)\n#-swank (disable-debugger) ; for CS Academy\n\n;; BEGIN_INSERTED_CONTENTS\n\n\n(declaim (ftype (function * (values fixnum &optional)) read-fixnum))\n(defun read-fixnum (&optional (in *standard-input*))\n \"NOTE: cannot read -2^62\"\n (declare #.OPT)\n (macrolet ((%read-byte ()\n `(the (unsigned-byte 8)\n #+swank (char-code (read-char in nil #\\Nul))\n #-swank (sb-impl::ansi-stream-read-byte in nil #.(char-code #\\Nul) nil))))\n (let* ((minus nil)\n (result (loop (let ((byte (%read-byte)))\n (cond ((<= 48 byte 57)\n (return (- byte 48)))\n ((zerop byte) ; #\\Nul\n (error \"Read EOF or #\\Nul.\"))\n ((= byte #.(char-code #\\-))\n (setq minus t)))))))\n (declare ((integer 0 #.most-positive-fixnum) result))\n (loop\n (let* ((byte (%read-byte)))\n (if (<= 48 byte 57)\n (setq result (+ (- byte 48)\n (* 10 (the (integer 0 #.(floor most-positive-fixnum 10))\n result))))\n (return (if minus (- result) result))))))))\n\n(declaim (ftype (function * (values simple-bit-vector &optional)) make-prime-table))\n(defun make-prime-table (sup)\n \"Returns a simple-bit-vector of length SUP, whose (0-based) i-th bit is 1 if i\nis prime and 0 otherwise.\n\nExample: (make-prime-table 10) => #*0011010100\"\n (declare (optimize (speed 3) (safety 0)))\n (check-type sup (integer 2 (#.array-total-size-limit)))\n (let ((table (make-array sup :element-type 'bit :initial-element 0))\n (sup/64 (ceiling sup 64)))\n ;; special treatment for p = 2\n (dotimes (i sup/64)\n (setf (sb-kernel:%vector-raw-bits table i) #xAAAAAAAAAAAAAAAA))\n (setf (sbit table 1) 0\n (sbit table 2) 1)\n ;; p >= 3\n (loop for p from 3 to (+ 1 (isqrt (- sup 1))) by 2\n when (= 1 (sbit table p))\n do (loop for composite from (* p p) below sup by p\n do (setf (sbit table composite) 0)))\n table))\n\n;; FIXME: Currently the element type of the resultant vector is (UNSIGNED-BYTE 62).\n(declaim (ftype (function * (values (simple-array (integer 0 #.most-positive-fixnum) (*))\n simple-bit-vector\n &optional))\n make-prime-sequence))\n(defun make-prime-sequence (sup)\n \"Returns the ascending sequence of primes smaller than SUP.\"\n (declare (optimize (speed 3) (safety 0)))\n (check-type sup (integer 2 (#.array-total-size-limit)))\n (let ((table (make-prime-table sup)))\n (let* ((length (count 1 table))\n (result (make-array length :element-type '(integer 0 #.most-positive-fixnum)))\n (index 0))\n (declare ((integer 0 #.most-positive-fixnum) length))\n (loop for x below sup\n when (= 1 (sbit table x))\n do (setf (aref result index) x)\n (incf index))\n (values result table))))\n\n(defstruct (prime-data (:constructor %make-prime-data (seq table)))\n (seq nil :type (simple-array (integer 0 #.most-positive-fixnum) (*)))\n (table nil :type simple-bit-vector))\n\n(defun make-prime-data (sup)\n (multiple-value-call #'%make-prime-data (make-prime-sequence sup)))\n\n(declaim (inline factorize)\n (ftype (function * (values list &optional)) factorize))\n(defun factorize (x prime-data)\n \"Returns the associative list of prime factors of X, which is composed\nof ( . ).
