[Algo round] In first round, interviewer asked DS/Algo problems. I was asked to two/three questions. For example, if you're given an array and prints all the triplets which are in arithmetic progression (AP).First I told the interviewer the brute force approach with O(n^3) time complexity. He asked me to optimize the solution, So I reduced that to O(nlogn) complexity, after that he again asked me to solve the problem in O(n^2), it took me some time but I solved it anyway. *It was time for second interview*.
