Your example said:

"write a function ved(n, m) that implements the 16 sutras* and uses  
them to return the result"

That's not a usable specification. The original question was:

"Given that fib(n) is equal to fib(n-1) + fib(n-2) write a fib  
function in any language"

Can you not see the difference? It doesn't matter that it's a  
well-known mathematical sequence. The required behaviour has been  
specified in the question. It could be rewritten as:

"Given that blarg(n) is equal to blarg(n-1) + blarg(n-2) write a blarg  
function in any language"

And it would still be solvable. Your question isn't a specification.  
It can't be solved without guesswork.

And besides, I don't think I'd really want to work with a programmer  
who didn't know what the Fibonacci sequence is :-)
