Question

I have to implements a function that takes a string as an input and finds the non-duplicate character from this string.

So an an example is if I pass string str = ‘DHCD’ it will return ‘DHC’ or str2 = ‘KLKLHHMO’ it will return ‘KLHMO’

Answer 1

A Linq approach:

public static string RemoveDuplicates(string input) {     return new string(input.ToCharArray().Distinct().ToArray()); }
