3539. Find Sum of Array Product of Magical Sequences Difficulty: Hard Topics:Array, Math, Dynamic Programming, Bit Manipulation, Combinatorics, Bitmask, Weekly Contest 448 You are given two integers, m and k, and an integer array nums. A sequence of integers seq is called magical if: seq has a size of m. 0 <= seq[i] < nums.length The binary representation of 2seq[0] + 2seq[1] + ... + 2seq[m - 1] has kset bits. The array product of this sequence is defined as prod(seq) = (nums[seq[0]] * nums[s...
