I solved the same problem using same logic. Once I directly tried to print the answers https://codeforces.net/contest/1715/submission/169136862 but got wrong answer on pretest 2.
While on other approach I stored them in an array and did the same https://codeforces.net/contest/1715/submission/169162093 and got the solution accepted. Why this happened?

That's the way of life of a coder sometimes you don't know why your code didn't got accepted and sometimes you don't know why your code got accepted but in both cases you know that it was just your fate. — Some Indian Guy on Youtube
