Write a function named "eliminate_duplicates" that takes an array of integers in random order
and eliminates all the duplicate integers in the array. The function should take two arguments:
(1) an array of integers;
(2) an integer that tells the number of cells in the array.
The function should not return a value, but if any duplicate integers are eliminated, then the function should
change the value of the argument that was passed to it so that the new value tells the number of distinct integers
in the array. Here is an example. Suppose the array passed to the function is as shown below, and the integer
passed as an argument to the function is 11.
0 1 2 3 4 5 6 7 8 9 10
58 | 26 | 91 | 26 | 70 | 70 | 91 | 58 | 58 | 58 | 66
Then the function should alter the array so that it looks like this:
0 1 2 3 4 5 6 7 8 9 10
58 | 26 | 91 | 70 | 66 | ?? | ?? | ?? | ?? | ?? | ??
and it should change the value of the argument so that it is 5 instead of 11 . The question marks in the cells
after the 5th cell indicate that it does not matter what numbers are in those cells when the function returns.
