WA in finding Longest Increasing subsequence in nlogn time complexity

I am practising a problem in hackerearth called Inversion Graphs.

I have solved using Longest Increasing subsequence in O(nlogn) algorithm.
My solution has passed all the test cases except the one test case #7.

Surprisingly, my solution is similar to the editorial one.

Thank you in advance :slight_smile:

I have implemented the same thing right? Any wrong in my code?
