      maybe it understand the line as ans[k] % (a[j] != 0)

          I tried if(a[j] == 0) return 0; in the for loop it give WA on test 5

          and diagnose : This application has requested the Runtime to terminate it in an unusual way.

          when the statement : a[i] >= 2

          ok so you used set in the start so a[j] might get to 0

          try to add if(j >= (int)a.size()) return 0; to the same for

          it get WA on test 5 instead of RTE

            Oh I see! a.size() may not be equal to n!!!! THX A Lot!!!
