Write a program in $C$ that inputs $n$ numbers, each between $0$ and $50,$ both inclusive. Save each number that was read in an array that was previously initialized to a value of $-1$ for all elements $($the maximum size of the array is $100).$ Assume a value of $-1$ indicates an array element is empty. You are then to process the array and remove duplicate elements from the array containing the numbers you input. Display the contents of the array to demonstrate that the duplicate input values were removed.

Note: do not display the array elements where the value is $-1$ and use ONLY ONE $1$D Array.

Sample Input:

$102688103892$

Sample Output

$10268389$
