I'm not good at Python but i'm trying to learn it, when i always submit a solution to Codeforces i always get run time error, but if i made the same solution in c++ it's okay and accepted, and here is an example. This is the problem set: https://codeforces.com/problemset/problem/1206/B

and here is my solution, all is well in my terminal window but i get run time error even in the first test case, i submit PyPy 3.6 or Python 3.7.2, i tried both

n = int(input())

ls = []

counter = 0 i = 0 for i in range(n): k = int(input()) # ls.append(k) if k > 1: counter += (k — 1) elif k < -1: counter += abs((k + 1)) else: counter += 1 print(counter) and thank you.
