The problem

You are given two 0-indexed integer arrays, nums1 and nums2, both having length n. You are allowed to perform a series of operations (possibly none).

Example

Input: nums1 = [1,2,7], nums2 = [4,5,3]
Output: 1
Explanation: In this example, an operation can be performed using index i = 2.

Python solution

Python

class Solution:
    def minOperations(self, nums1: List[int], nums2: List[int]) -> int:
        def f(x: int, y: int) -> int:
            cnt = 0
            for a, b in zip(nums1[:-1], nums2[:-1]):
                if a <= x and b <= y:
                    continue
                if not (a <= y and b <= x):
                    return -1
                cnt += 1
            return cnt

        a, b = f(nums1[-1], nums2[-1]), f(nums2[-1], nums1[-1])
        return -1 if a + b == -2 else min(a, b + 1)
