Question

What would happen if we call gcd(m,n) with m positive and n negative in the following definition?
def gcd(m,n):
if m < n:
(m,n) = (n,m)
if (m % n) == 0:
return(n)
else:
diff = m-n
return (gcd(max(n,diff),min(n,diff)))

Hi, the best way to know it is to try it, but if you want to make sure a number is positive, use abs(number)
