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
Example 2:
Input: nums = [1,2,1] Output: 0
Example 3:
Input: nums = [3,2,3,4] Output: 10
Example 4:
Input: nums = [3,6,2,3] Output: 8
Constraints:
3 <= nums.length <= 104
1 <= nums[i] <= 106
