Imagine, you have an array of integers of size N. At each index of this array is a unique integer fr…

But in your nested loop, i will always be greater than j.

Your outer loop is starting i from 0. And your inner loop is starting j from i. While i is at any value, j will start from i and will be incremented until it is len(x).

This kind of approach will not work here. You will get TLE.
You have to a more efficient way to solve the problem.
You can learn counting inversions with merge sort after you have learnt merge sort.

but i expect tle , everyone is getting ac with n sqaure, how is it possible at 1e5… i was cheking but my code got ac. i think test case is still weak . chk the shortest code

The shortest code would also get a WA now for the newly added test case. And if same bug in that code was corrected (which is also present in your code), then it would get a TLE for both of the last two cases.

But since that submission is from a contest, we won’t rejudge it.
