WebApr 14, 2024 · You have to divide the array into k contiguous subarrays in such a way that the bitwise AND of all subarray sums is maximized. For example with array= [30,15,26,16,21] and k=3, consider all partitions: (30) & (15) & (26+16+21) = 14 (30) & (15+26) & (16+21) = 0 (30) & (15+26+16) & (21) = 16 (30+15) & (26+16) & (21) = 0 … WebThe bitwise OR of a subarray is the bitwise OR of each integer in the subarray.

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.
