Coding Interview Round


You will answer coding-related questions in this round. It lasts for an average of 45 minutes.

Interview Questions

  • You are given an array/list of unsorted ARR of N integers. Return the length of the longest consecutive sequence. The consecutive sentence in the form ['NUM', 'NUM' + 1, 'NUM' + 2, ..., 'NUM' + L], where 'NUM' is the starting integer of the sequence while L + 1 is the length of that sequence. If we find duplicates in the array, we will consider only one of them in a consecutive sequence. Like, for the given ARR [9,5,4,9,10,10,6], output = 3. Here, the longest consecutive sequence is 4, 5, and 6. Can you also solve this in 0(N) space complexity and 0(N) time?
  • A group of friends went on a trip and lent each other money for various purposes. The tuple (X, Y, Z) represents each transaction, i.e., person X gave person y $Z. Given a list of 'N' number of transactions, return the minimum number of transactions required to settle the debt.
