C++ function: Assume that the vectors arriving at the function were passed using the const keyword, so the function cannot modify them. In addition, we will put the restriction that within the function we will NOT create vectors or new arrangements. To solve the problem, in this case you will have to go through the arrays "simultaneously" avoiding the zeros and detecting that the corresponding nonzero elements are equal. 

Example: (42, 0, 0, 0, 53) contains the same sequence as (42, 53)
