Given the array nums, for each nums[i] find out how many numbers in the array are smaller than it. That is, for each nums[i] you have to count the number of valid j's such that j != i and nums[j] < nums[i].

\n\n

Return the answer in an array.

\n

Example 1:

\n\n
\nInput: nums = [8,1,2,2,3]\nOutput: [4,0,1,1,3]\nExplanation: \nFor nums[0]=8 there exist four smaller numbers than it (1, 2, 2 and 3). \nFor nums[1]=1 does not exist any smaller number than it.\nFor nums[2]=2 there exist one smaller number than it (1). \nFor nums[3]=2 there exist one smaller number than it (1). \nFor nums[4]=3 there exist three smaller numbers than it (1, 2 and 2).\n
\n\n

Example 2:

\n\n
\nInput: nums = [6,5,4,8]\nOutput: [2,1,0,3]\n
\n\n

Example 3:

\n\n
\nInput: nums = [7,7,7,7]\nOutput: [0,0,0,0]\n

给你一个数组 nums,对于其中每个元素 nums[i],请你统计数组中比它小的所有数字的数目。

\n\n

换而言之,对于每个 nums[i] 你必须计算出有效的 j 的数量,其中 j 满足 j != i nums[j] < nums[i] 。

\n\n

以数组形式返回答案。

\n\n

示例 1:

\n\n
输入:nums = [8,1,2,2,3]\n输出:[4,0,1,1,3]\n解释: \n对于 nums[0]=8 存在四个比它小的数字:(1,2,2 和 3)。 \n对于 nums[1]=1 不存在比它小的数字。\n对于 nums[2]=2 存在一个比它小的数字:(1)。 \n对于 nums[3]=2 存在一个比它小的数字:(1)。 \n对于 nums[4]=3 存在三个比它小的数字:(1,2 和 2)。\n
\n\n

示例 2:

\n\n
输入:nums = [6,5,4,8]\n输出:[2,1,0,3]\n
\n\n

示例 3:

\n\n
输入:nums = [7,7,7,7]\n输出:[0,0,0,0]\n
