Codeforces Weird Bug?
By NazihBaydoun, history, 4 weeks ago, In English

Hello Everyone! Today I encountered a weird bug for the first time. So basically I was submitting some code to a problem and that's when I encountered this weird bug where I got wrong answer on test case 1 even though when I copied the input and tried it in my code editor it passed the first testcase? Can anyone see why this happened pls. Thank you. Here's the problem and the submission: [problem:https://mirror.codeforces.com/problemset/problem/2191/B] and [submission:https://mirror.codeforces.com/contest/2191/submission/368125504].

set does not keep elements in a particular order, so it keeps changing with different versions, just use

l1 = sorted(list(set(a[:i + 1])))

similarly for l2, should not give different answers then
