    611 - Valid Triangle Number.

    Medium

    Given an integer array nums, return the number of triplets chosen from the array that can make triangles if we take them as side lengths of a triangle.

    Example 1:

    Input: nums = 2,2,3,4

    Output: 3

    Explanation: Valid combinations are:

    2,3,4 (using the first 2)

    2,3,4 (using the second 2)

    2,2,3

    Example 2:

    Input: nums = 4,2,3,4

    Output: 4

    Constraints:

    • 1 <= nums.length <= 1000

    • 0 <= nums[i] <= 1000
