Given an array of N and a number n, remove all occurance of that number from an array if number is present
Example 1:
arr={1,2,3,4,5}
num=4 (number to be removed)
Output: {1,2,3,5,-1} Since 4 is removed, 5 will take it place. We will fill up left over with -1
Example 2:
arr={1,2,3,4,5}
num =6 (number to be removed,but is not present)
Output: {1,2,3,4,5} Since element was not present, nothing will be removed.
Example 3:
arr={1,2,3,4,5,4}
num=4 (number to be removed)
Output :{1,2,3,5,-1,-1} Since both 4 are removed, 5 will go forward and then the left over place will be filled up by -1
