In the recent contest Educational Codeforces Round 147 (Rated for Div. 2), Question C. I faced ambiguity when compiling my code with GNU G++17 7.3.0. Here is my submitted code 202889532 and 202887839

When line 35, which is an output statement, is commented out. I get different return value

If I print an empty string "", my return value, and hence output changes.

Please have a look! MikeMirzayanov
