Hi Few hours back I gave Amazon OA and got the following 2 questions.\n\n1) Algorithm Swaps\n2) Gifting Groups.\n\nI was able to solve 1 with all the testcases passed but got timed out during 2. Within 30 minutes I got the rejection email. I have seen few people getting called by solving 1 prob. Any possible reason why I got rejected?\nAlso for problem 1, I saw the problem before in geekforgeeks using merge sort & inversion count. I coded in the same way. Is this a reason for rejection?
