You are given a 0-indexed integer array nums. You can rearrange the elements of nums to any order (including the given order).

\n\n

Let prefix be the array containing the prefix sums of nums after rearranging it. In other words, prefix[i] is the sum of the elements from 0 to i in nums after rearranging it. The score of nums is the number of positive integers in the array prefix.

\n\n

Return the maximum score you can achieve.

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [2,-1,0,1,-3,3,-3]\nOutput: 6\nExplanation: We can rearrange the array into nums = [2,3,1,-1,-3,0,-3].\nprefix = [2,5,6,5,2,2,-1], so the score is 6.\nIt can be shown that 6 is the maximum score we can obtain.\n
\n\n

Example 2:

\n\n
\nInput: nums = [-2,-3,0]\nOutput: 0\nExplanation: Any rearrangement of the array will result in a score of 0.\n
\n\n

给你一个下标从 0 开始的整数数组 nums 。你可以将 nums 中的元素按 任意顺序 重排(包括给定顺序)。

\n\n

prefix 为一个数组,它包含了 nums 重新排列后的前缀和。换句话说,prefix[i]nums 重新排列后下标从 0i 的元素之和。nums分数prefix 数组中正整数的个数。

\n\n

返回可以得到的最大分数。

\n\n

 

\n\n

示例 1:

\n\n
输入:nums = [2,-1,0,1,-3,3,-3]\n输出:6\n解释:数组重排为 nums = [2,3,1,-1,-3,0,-3] 。\nprefix = [2,5,6,5,2,2,-1] ,分数为 6 。\n可以证明 6 是能够得到的最大分数。\n
\n\n

示例 2:

\n\n
输入:nums = [-2,-3,0]\n输出:0\n解释:不管怎么重排数组得到的分数都是 0 。\n
