Largest Perimeter Triangle
Easy
You receive an integer array nums, provide the largest perimeter of a triangle with a non-zero area, formed from three of these lengths. If it is imvalid to form any triangle of a non-zero area, provide 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 provide 0.
Constraints
3 <= nums.length <= 10^41 <= nums[i] <= 10^6
