    976 - Largest Perimeter Triangle.

    Easy

    Given an integer array nums, return the largest perimeter of a triangle with a non-zero area, formed from three of these lengths. If it is impossible to form any triangle of a non-zero area, return 0.

    Example 1:

    Input: nums = 2,1,2

    Output: 5

    Explanation: You can form a triangle with three side lengths: 1, 2, and 2.

    Example 2:

    Input: nums = 1,2,1,10

    Output: 0

    Explanation:

    You cannot use the side lengths 1, 1, and 2 to form a triangle.

    You cannot use the side lengths 1, 1, and 10 to form a triangle.

    You cannot use the side lengths 1, 2, and 10 to form a triangle.

    As we cannot use any three side lengths to form a triangle of non-zero area, we return 0.

    Constraints:

    • <code>3 <= nums.length <= 10<sup>4</sup></code>

    • <code>1 <= numsi<= 10<sup>6</sup></code>
