Lock: Starting with the strongest pair, go through the pairs of candidates in order and “lock in” each pair to the candidate graph, so long as locking in that pair does not create a cycle in the graph. As far as I can see, the basic algorithm of the function is this: This "// This intput doesn't change through recursions" (referring to start in the check_loop function) sounds like a problem. check50 output for the lock_pairs function::( lock_pairs locks all pairs when no cycles lock_pairs did not lock all pairs :) lock_pairs skips final pair if it creates cycle :) lock_pairs skips middle pair if it creates a cycle ファイルのさらに下の方には、vote、record_preference、add_pairs、sort_pairs、lock_pairs、およびprint_winner関数が空白のままであることがわかります。あなたが作成するものです！ 仕様.

Can't determine the problem with my tideman program - check50 fails at lock_pairs function, says I didn't correctly lock all non-cyclical pairs. In the code I am locking in a pair and then retrospectively checking if that leaves at least one column in the locked[][] matrix with only false rows. By this time you should have completed pairs array(add_pairs function), which has all necessary winners & losers(as pair). If that is possible, there is a cycle and you We'll make a recursive call has_cycle(original_winner /* this doesn't change */, pair[i].
