Generating all subarrays of an array
WebIn general, for an array/string of size n, there are n*(n+1)/2 non-empty subarrays/substrings. How to generate all subarrays? We can run two nested loops; The outer loop picks the starting element. The inner loop considers all elements on right of the picked starting element as ending element of subarray. WebAug 11, 2024 · The idea here is, we will try to find the number of AND values (sub-arrays with bit-wise and (&)) with i th bit set. Let us suppose, there is ‘S i ‘ number of sub-arrays with i th bit set. For, i th bit, the sum can be updated as sum += (2 i * S). We will break the task into multiple steps. At each step, we will try to find the number of ...
