You are given a 0-indexed integer array nums of size 3 which can form the sides of a triangle.
Return a string representing the type of triangle that can be formed or "none" if it cannot form a triangle.
Examples
Example 1
Input: nums = [3,3,3]
Output: "equilateral"
Explanation: Since all the sides are of equal length, therefore, it will form an equilateral triangle.
Example 2
Input: nums = [3,4,5]
Output: "scalene"
Explanation:
nums[0] + nums[1] = 3 + 4 = 7, which is greater than nums[2] = 5.
nums[0] + nums[2] = 3 + 5 = 8, which is greater than nums[1] = 4.
nums[1] + nums[2] = 4 + 5 = 9, which is greater than nums[0] = 3.
Since the sum of the two sides is greater than the third side for all three cases, therefore, it can form a triangle.
As all the sides are of different lengths, it will form a scalene triangle.
