3024 - Type of Triangle.

Easy

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”

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.

Constraints:

  • nums.length == 3
  • 1 <= nums[i] <= 100
