Going through some blogs regarding the cause of the difference in output between judge and local terminal, I saw majorly the Out of Bound error. But I have looked across my code multiple times, not able to find the generation of such an exception.

Problem: 1335E1 - Three Blocks Palindrome (easy version). My submission: 79635901

For test case 1, the output is different,

Participant's output: 6 2 3 0 0 2

Output on the local machine: 7 2 4 1 1 3

I suspect the error may lie somewhere in the implementation of sets. Please help me through if anyone catches the issue. Cheers.
