WebFor Loop (C++17 64 bit): 3736 ms Actually 64 bit Bitset (C++17 64 bit): 69ms Ah... 3736/69 ~= 64. There we go :) Running the benchmarks with MAXN=1e5 and iters=1e5 makes it … Web之前做过一道类似的题目还会更难一点，这里的话用到了bitset优化，以某一行i作为一个标准去异或其他所有行，如果异或行j出来的值val取min(val,n-val)，就是将行j变到和行i完全相似或者相反需要变的最少的点数。 ...
WebBased on the solution, the answer is 12. But if we take a subrectangle with ( h, w) = ( 4, 3) and upper-left corner placing on ( 1, 1), the maximum value inside is 21, which is not the global maximum value (30). So if Joe chooses this subrectangle, Michael will lose. I think the answer should be 16. Web1 The package for this problem was not updated by the problem writer or Codeforces administration after we've upgraded the judging servers. To adjust the time limit constraint, a solution execution time will be multiplied by 2. For example, if your solution works for 400 ms on judging servers, then the value 800 ms will be displayed and used to ...
WebA faster Python with Bitset and BST in the stdlib — F#.
