I and many peoples are getting TLE on Catching Cheaters problem.

The intended solution in pypy3 implementation is getting TLE: https://codeforces.net/contest/1447/submission/98682330

There aren't any accepted solutions by Python3, Python2, Javascript.

The solution with the fastest execution time in C++ is 62 ms, which in python means 62 * 30 > 1000ms.

My accepted solution is 966 ms. Very tight

At least the time limit should be 1.5 sec. I didn't get the reason for making it so tight?
