You are given two arrays nums1 and nums2 consisting of positive integers.
You have to replace all the 0's in both arrays with strictly positive integers such that the sum of elements of both arrays becomes equal.
Return the minimum equal sum you can obtain, or -1 if it is impossible.
\n
Example 1:
\n\n\nInput: nums1 = [3,2,0,1,0], nums2 = [6,5,0]\nOutput: 12\nExplanation: We can replace 0's in the following way:\n- Replace the two 0's in nums1 with the values 2 and 4. The resulting array is nums1 = [3,2,2,1,4].\n- Replace the 0 in nums2 with the value 1. The resulting array is nums2 = [6,5,1].\nBoth arrays have an equal sum of 12. It can be shown that it is the minimum sum we can obtain.\n\n\n
Example 2:
\n\n\nInput: nums1 = [2,0,2,0], nums2 = [1,4]\nOutput: -1\nExplanation: It is impossible to make the sum of both arrays equal.\n\n\n
\n
Constraints:
\n\n1 <= nums1.length, nums2.length <= 1050 <= nums1[i], nums2[i] <= 106给你两个由正整数和 0 组成的数组 nums1 和 nums2 。
你必须将两个数组中的 所有 0 替换为 严格 正整数，并且满足两个数组中所有元素的和 相等 。
返回 最小 相等和 ，如果无法使两数组相等，则返回 -1 。
\n\n
示例 1：
\n\n\n输入：nums1 = [3,2,0,1,0], nums2 = [6,5,0]\n输出：12\n解释：可以按下述方式替换数组中的 0 ：\n- 用 2 和 4 替换 nums1 中的两个 0 。得到 nums1 = [3,2,2,1,4] 。\n- 用 1 替换 nums2 中的一个 0 。得到 nums2 = [6,5,1] 。\n两个数组的元素和相等，都等于 12 。可以证明这是可以获得的最小相等和。\n\n\n
示例 2：
\n\n\n输入：nums1 = [2,0,2,0], nums2 = [1,4]\n输出：-1\n解释：无法使两个数组的和相等。\n\n\n
\n\n
提示：
\n\n1 <= nums1.length, nums2.length <= 1050 <= nums1[i], nums2[i] <= 106-1 if there was no 0 in the array with the smaller sum of elements.",
"Otherwise, how can you update the value of exactly one of these 1’s to make the sum of the two arrays equal?",
"Consider we replace all the 0’s with 1’s on both arrays, the answer will be -1 if there was no 0 in the array with the smaller sum of elements.",
"Otherwise, how can you update the value of exactly one of these 1’s to make the sum of the two arrays equal?"
