Linear-Time Algorithm To Remove Duplicate Characters From A String | C Programming Example

How to remove the duplicate occurrences of characters from a string in C, using a high performance linear-time algorithm. This algorithm is more efficient than an alternative algorithm created in this video: https://www.youtube.com/watch?v=4iaYlp-axac, though notably it uses an additional array to keep track of duplicate characters and as a result is less space-efficient in that it uses more memory.
