2961. Double Modular Exponentiation

You are given a 0-indexed 2D array variables where variables[i] = [ai, bi, ci, mi], and an integer target. An index i is good if the following formula holds: - 0 <= i < variables.length - ((aibi % 10)ci) % mi == target Return an array consisting of good indices in any order. Example 1: Input: variables = [[2,3,3,10],[3,3,3,1],[6,1,1,4]], target = 2 Output: [0,2] Explanation: For each index
