Hi,
I m playing around with extended euclids algorithm from Knuth. I m
trying to build a function with a function inside it.
def exteuclid(m,n):
a,a1,b,b1,c,d = 0,1,1,0,m,n
def euclid(c,d):
q = c /d
r = c % d
if r == 0:
print a,b
return d
else:
print a1,a,b1,b,c,d,q,r
t = b1
b = t - q * b
a = t - q * a
c,d,a1,b1 = d,r,a,b
return euclid(c,d)
return euclid(c,d)
Unfortunately this doesnt work since a,a1,b,b1 arent declared in the
function. Is there a way to make these variables accessible to the
euclid function. Or is there a better way to design this function?
Many Thanks in advance,
Nathan
