1365. How Many Numbers Are Smaller Than the Current Numberopen in new window

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].

Return the answer in an array.

Example 1:

Input: nums = [8,1,2,2,3]

Output: [4,0,1,1,3]

Explanation:

  • For nums[0]=8 there exist four smaller numbers than it (1, 2, 2 and 3).

  • For nums[1]=1 does not exist any smaller number than it.

  • For nums[2]=2 there exist one smaller number than it (1).

  • For nums[3]=2 there exist one smaller number than it (1).

  • For nums[4]=3 there exist three smaller numbers than it (1, 2 and 2).

Example 2:

Input: nums = [6,5,4,8]

Output: [2,1,0,3]

Example 3:

Input: nums = [7,7,7,7]

Output: [0,0,0,0]

Constraints

  • 2 <= nums.length <= 500
  • 0 <= nums[i] <= 100
