+ * 3024. Type of Triangle
+ * https://leetcode.com/problems/type-of-triangle/
+ * Difficulty: 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.
