The interview was held on Amazon Chime.\nThe interviewer started with asking me to describe any project that I had worked on. This was followed by 2 coding questions.\n\n**Question 1**\nGiven a stream of numbers, find the number of groups that can be formed using the maximum number of elements such that each group satisfies the following constraints -\n\n**Group constraints**\n1. Each group can have only 2 or 3 elements\n2. The sum of elements in the group should be divisible by 3\n\nEx: 1,2,3,5,7,12,14,18,24\nAns: 3\n[(1,2,3),(5,7,12),(18,24)]\n\nPS: You can skip elements also\n\n**Question 2** \nGiven a 2D matrix consisiting of only 0s and 1s where each row and column is sorted in the non-increasing order, give an optimal solution to count the number of 0s.\n\nEx: \n1 1 1 0\n1 1 0 0\n1 0 0 0\n0 0 0 0\n\nAns: 10\n\nThe first question didn\'t go well :( but a very big thank you to the leetcode community! I\'ve improved a lot by practicising on leetcode and hope to continue to do so.
