Provide tags and a correct Python 3 solution for this coding contest problem. You are given a table consisting of n rows and m columns. Numbers in each row form a permutation of integers from 1 to m. You are allowed to pick two elements in one row and swap them, but no more than once for each row. Also, no more than...
