Ramanunam Numbers calculator

There are two modes of usage for the program
If only the numbers are needed then the first else
if verbose output is needed then the second mode
1) a = ramanujam (n)
2) ramanujam (n)
The first calling method returns resultant sum
Diophantine equation [sum = a^3 + b^3 = c^3 + d^3]
The second calling method prints all four variables
a,b,c,d and sum which forms the Diophantine equation
