1775 - Equal Sum Arrays With Minimum Number of Operations.

Medium

You are given two arrays of integers nums1 and nums2, possibly of different lengths. The values in the arrays are between 1 and 6, inclusive.

In one operation, you can change any integer’s value in any of the arrays to any value between 1 and 6, inclusive.

Return the minimum number of operations required to make the sum of values in nums1 equal to the sum of values in nums2. Return -1 if it is not possible to make the sum of the two arrays equal.

Example 1:

Input: nums1 = [1,2,3,4,5,6], nums2 = [1,1,2,2,2,2]

Output: 3

Explanation: You can make the sums of nums1 and nums2 equal with 3 operations. All indices are 0-indexed.

  • Change nums2[0] to 6. nums1 = [1,2,3,4,5,6], nums2 = [6 ,1,2,2,2,2].

  • Change nums1[5] to 1. nums1 = [1,2,3,4,5, 1 ], nums2 = [6,1,2,2,2,2].

  • Change nums1[2] to 2. nums1 = [1,2, 2 ,4,5,1], nums2 = [6,1,2,2,2,2].

Example 2:

Input: nums1 = [1,1,1,1,1,1,1], nums2 = [6]

Output: -1

Explanation: There is no way to decrease the sum of nums1 or to increase the sum of nums2 to make them equal.

Example 3:

Input: nums1 = [6,6], nums2 = [1]

Output: 3

Explanation: You can make the sums of nums1 and nums2 equal with 3 operations. All indices are 0-indexed.

  • Change nums1[0] to 2. nums1 = [2 ,6], nums2 = [1].

  • Change nums1[1] to 2. nums1 = [2, 2 ], nums2 = [1].

  • Change nums2[0] to 4. nums1 = [2,2], nums2 = [4 ].

Constraints:

  • 1 <= nums1.length, nums2.length <= 105
  • 1 <= nums1[i], nums2[i] <= 6
