Here's my C# implementation ✌ LINQ One-Liner〰 Console.WriteLine(string.Join(", ", new int[] { 2, 5, 7, 5, 6, 1, 3, 2, 6 }.Distinct())); Well I think it's kinda rude here to use LINQ for this kind of challenge. Anyway, enjoy! https://code.sololearn.com/cc2SSFeuUMr3/?ref=app

For Python, I think "set" will do the trick.

There are many ways to do this,the naive way is use two pointers, do loops to check every single number in array;you can also use HashSet, which is used to remove duplicate elements in the industry field.
