Asked in company
You are given an array consisting of N integers. You need to find the number of k-element subsequences of the given array where the bitwise AND of the subsequence's elements is maximal. Also, find the maximal AND value.
Example:
Let the array be [1, 3, 6, 7] and K=3. The possible k-element subsequences of the given array are: {1, 3, 6}, {1, 3, 7}, {1, 6, 7}, {3, 6, 7}. Applying AND operation on all possible subsequences we get values: 0, 1, 0, 2 respectively. The maximal AND value of these subsequences is 2, and only 1 subsequence {3, 6, 7} has this value.
Problem approach
Step 1 : I first applied bubble sort. It was not good enough.
Step 2 : Interviewer asked me to optimise the solution.
Step 3 : Then i gave solution with merge sort and interviewer was happy.
