/* This is the "gcd" function , which takes two input. first
one is the array and the second one is the length of the array.
Now to calculate the gcd of two elements we fin the maximum of
the two elements, and then iterate from maximum value down to 1,
and check whether the particular value divides the two elements.
And in this way we can calculate the gcd of the whole array.
