3858. Minimum Bitwise OR From Grid

You are given a 2D integer array grid of size m x n. You must select exactly one integer from each row of the grid. Return an integer denoting the minimum possible bitwise OR of the selected integers from each row. Example 1: Input: grid = [[1,5],[2,4]] Output: 3 Explanation: - Choose 1 from the first row and 2 from the second row. - The bitwise OR of 1 | 2 = 3​​​​​​​, which is the minim
