You are given an array of integers nums. Consider the following operation:
nums and define the score of the operation as the sum of these two elements.You can perform this operation until nums contains fewer than two elements. Additionally, the same score must be achieved in all operations.
Return the maximum number of operations you can perform.
\n\n\n
Example 1:
\n\nInput: nums = [3,2,1,4,5]
\n\nOutput: 2
\n\nExplanation:
\n\n3 + 2 = 5. After this operation, nums = [1,4,5].4 + 1 = 5, the same as the previous operation. After this operation, nums = [5].Example 2:
\n\nInput: nums = [1,5,3,3,4,1,3,2,2,3]
\n\nOutput: 2
\n\nExplanation:
\n\n1 + 5 = 6. After this operation, nums = [3,3,4,1,3,2,2,3].3 + 3 = 6, the same as the previous operation. After this operation, nums = [4,1,3,2,2,3].4 + 1 = 5, which is different from the previous scores.Example 3:
\n\nInput: nums = [5,3]
\n\nOutput: 1
\n\n
Constraints:
\n\n2 <= nums.length <= 1001 <= nums[i] <= 1000给你一个整数数组 nums ，如果 nums 至少 包含 2 个元素，你可以执行以下操作：
nums 中的前两个元素并将它们删除。一次操作的 分数 是被删除元素的和。
\n\n在确保 所有操作分数相同 的前提下，请你求出 最多 能进行多少次操作。
\n\n请你返回按照上述要求 最多 可以进行的操作次数。
\n\n\n\n
示例 1：
\n\n\n输入：nums = [3,2,1,4,5]\n输出：2\n解释：我们执行以下操作：\n- 删除前两个元素，分数为 3 + 2 = 5 ，nums = [1,4,5] 。\n- 删除前两个元素，分数为 1 + 4 = 5 ，nums = [5] 。\n由于只剩下 1 个元素，我们无法继续进行任何操作。\n\n
示例 2：
\n\n\n输入：nums = [3,2,6,1,4]\n输出：1\n解释：我们执行以下操作：\n- 删除前两个元素，分数为 3 + 2 = 5 ，nums = [6,1,4] 。\n由于下一次操作的分数与前一次不相等，我们无法继续进行任何操作。\n\n\n
