Write a function which accepts an integer array and its size and modifies the array in the following manner. 
# 1) If the elements of index i and (i+1) are equal then, double the value at index i
# and replace the element at index (i+1) with 0.
# 
#     2) If the element at index i is 0, then ignore it.
# 
#     3) Any number (element in an array) must be modified only once.
# 
#     4) At the end, shift all the zeros (0s) to the right of the array and remaining
# nonzeros to the left of the array.
