 ## Description
+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: a = "11", b = "1"
-Output: "100"
+Input: nums = [3,3,3]
+Output: "equilateral"
+Explanation: Since all the sides are of equal length, therefore, it will form an equilateral triangle.

-Type of Triangle
-```go

-
+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.
+```
