Hello, Codeforces. Today I solved problems in problemset and found interesting thing. Well known that when you create problems in polygon you can set custom output to tests in statements. It is used in many problems where you must output algorithm to solve. But, when you submit your code, you can see your output to test and jury's answer. The custom output on examples is used so that the participant does not understand the algorithm for solving by examples, but the jury's answers can lead the participant to the correct algorithm. For example, lets see second test from problem 1479C - Continuous City.

The output in statements:

Spoiler

The output in submission:

Spoiler

As we can see, outputs differ. I think this is serious bug, which can lead participants to jury's algorithm, and this should be fixed asap

This used to be a problem, but at some point it was fixed so that, while the contest is running, you can't see jury's answers anymore; you can only see your answer and the checker log.
