WebMar 20, 2024 · Dynamic Programming Approach O (n*m): We define a number m such that m = pow (2, (log2 (max (arr))+1)) – 1. This number is actually the maximum value any XOR subset will acquire. We get this number by counting bits in largest number. We create a 2D array dp [n+1] [m+1], such that dp [i] [j] equals to the number of subsets having XOR … WebNov 2, 2024 · To find the number of bits in a number, we must count the number of steps taken to go from x to 0 by turning the maximum number of the rightmost bits off in a step. Where x is a number in the range [0, N]. Approach: This will be done by the bitwise-and operation between x and x – 1.
