Given two integer arrays arr1 and arr2, return the minimum number of operations (possibly zero) needed to make arr1 strictly increasing. In one operation, you can choose two indices 0 <= i < arr1.length and 0 <= j < arr2.length and do the assignment arr1[i] = arr2[j]. If there is no way to make arr1 strictly increasing, return -1. Example 1: Input: arr1 = [1,5,3,6,7], arr2 = [1,3,2,4] Output: 1 Explanation: Replace 5 with 2, then arr1 = [1, 2, 3, 6, 7]. Example 2: Input: arr1 = [1,5,3,6,7], arr2 = [4,3,1] Output: 2 Explanation: Replace 5 with 3 and then replace 3 with 4. arr1 = [1, 3, 4, 6, 7]. Example 3: Input: arr1 = [1,5,3,6,7], arr2 = [1,6,3,3] Output: -1 Explanation: You can't make arr1 strictly increasing. Constraints: 1 <= arr1.length, arr2.length <= 2000 0 <= arr1[i], arr2[i] <= 10^9
