This is an interesting problem from LeetCode. It is one of the Medium level problems. It has been asked 9 times in Google and twice in the Amazon coding interview rounds.

So What Is The Problem?

We have two integer sequences A and B of the same non-zero length.

We are allowed to swap elements A[i] and B[i]. Note that both elements are in the same index position in their respective sequences.

At the end of some number of swaps, A and B are both strictly increasing.

A sequence is strictly increasing if and only if
A[0] < A[1] <A[2]< … < A[A.length — 1]
