Write a program that takes in an array and delets the repeats in that array. Using these functions and a delete repeats function. Do not use the Null Character to detect the end of array. $($this$,$ after all, could be an array of ints$)$

Use a find function that returns a pointer to the location of the first occurrence of a key. $($or a nullptr if not found$)$

Use ONLY the pointer notation:

you will NOT use the $[]$ operator.

you will not use the ugly $*($p $+$ i$)$ notation.

use if you need to access a cell in the array, get a walker and point to the cell you want to access.

you may use walker $=$ walker $+1$ or walker $=$ walker $+$ i$.$
