Write a C method named isPrepareSArray that returns 1 if its array argument is a PrepareS array, otherwise return 0.

A PrepareS array has the following property.
a[0] = a[1] + a[2] = a[3]+a[4]+a[5] = a[6] + a[7] + a[8]+ a[9] = ....

Then length of PrepareS array must be n*(n+1)/2 for some n.
Write a C method named isPrepareSArray that returns 1 if its array argument is a PrepareS array, otherwise return 0.

Some Tracings:

2,1,1 = is PrepareS array, returns 1

2,1,1,4,-1,-1 is PrepareS array, returns 1

3,1,2,3,0 is NOT PrepareS Array, returns 0 because it does not satisfy n*(n+1)/2 length.
