LeetCode ProblemFind Subarray With Bitwise OR Closest to K
You are given an array nums and an integer k. You need to find a subarray of nums such that the absolute difference between k and the bitwise OR of the subarray elements is as small as possible. In other words, select a subarray nums[l..r] such that |k - (nums[l] OR nums[l + 1] ... OR nums[r])| is minimum. Return the minimum possible value of the absolute difference. A subarray is a contiguous non-empty sequence of elements within an array.
