Delete Repeats

[theDon85]

I have to write a function that takes in an array of characters, finds the characters that are repeated, delete them, and move the rest of the characters up one position. Should be easy, but i have been struggling with it, trying various combinations of loops and what not but cant seem to find a way to make it work.

Anything to point me in the write direction would be appreciated.
