WebApproach: Click here to read about the recursive solution - Print all subarrays using recursion Use three nested loops. Outer loops will decide the starting point of a sub-array, call it as startPoint. First inner loops will decide the group size (sub-array size). Group size starting from 1 and goes up array size. Let's call is as grps. WebThe bitwise OR of a subarray is the bitwise OR of each integer in the subarray. The bitwise OR of a subarray of one integer is that integer. A subarrayis a contiguous non …
WebAug 5, 2024 · The most efficient and simple way to deal with is problem is: Step 1: calculate the xor of prefixes : xorArr [0] = arr [0] #here arr = [13,8,5,3,3] for i in range (1, n): xorArr [i] = xorArr [i - 1] ^ arr [i] Step 2: Check if at any point xorArr [i]=0, if yes then arr [:i+1] is one subarray whose xor is zero: WebApr 19, 2024 · BITWISE AND of all subarrays of given Integer array The question is incomplete.

WebAnd bitwise ORs of all the elements for all the subarrays will be 1,2,3,3,3,3 respectively. So, the count of distinct OR will be 3. Sample Input 2: 1 2 1 5 Sample Output 2: 2 Explanation for sample input 2: The possible subarrays of {1,5} are {1},{5},{1,5}. And bitwise ORs of the elements for all the subarrays will be 1,5,5 respectively.
WebThe idea is to maintain a maximum (positive-sum) subarray “ending” at each index of the given array. This subarray is either empty (in which case its sum is zero) or consists of one more element than the maximum subarray ending at the previous index.
