It looks like djm03178 (and, to be fair, some other users too) uses some kind of automated tools that detect solutions using unordered_set or unordered_map, and then send hack tests in bulk. From my perspective, hacks that exploit programming language's internal bugs are generally unsportsm...

In order to cut off efficient solutions from inefficient ones in this problem, the time limit is rather strict. Prefer to use compiled statically typed languages (e.g. C++). If you use Python, then submit solutions on PyPy. Try to write an efficient solution. ...
Output two lines, each consisting of13 upper-case English characters, representing the rows of the grid. If there are multiple solutions, print any of them. If there is no solution print "Impossible". Examples input ABCDEFGHIJKLMNOPQRSGTUVWXYZ ...
Input The only line contains an integer n (12 ≤ n ≤ 106). Output Output two composite integers x and y (1 < x, y < n) such that x + y = n. If there are multiple solutions, you can output any of them. ...
On the first line print a single integer — the minimal possible m. On each of the next n lines print four space separated integers representing the i-th set. Neither the order of the sets nor the order of integers within a set is important. If there are multiple possible solutions with...
