Type of Triangle
You are given a 0-indexed integer array nums of size 3 which can form the sides of a triangle.
- A triangle is called equilateral if it has all sides of equal length.
- A triangle is called isosceles if it has exactly two sides of equal length.
- A triangle is called scalene if all its sides are of different lengths.
Return a string representing the type of triangle that can be formed, or "none" if it cannot form a triangle.
Example 1
Input
nums = [3,3,3]Output
"equilateral"Since all the sides are of equal length, it will form an equilateral triangle.
Example 2
Input
nums = [3,4,5]Output
"scalene"The sum of any two sides is greater than the third side, and all side lengths are different, so it forms a scalene triangle.
Constraints
- nums.length == 3
- 1 <= nums[i] <= 100
