It is part of an algorithum:
#!/usr/bin/env python
def A(k, x1, x2, x3, x4, x5):
def B():
k = k - 1;
B.out=A.out=A(k, B, x1, x2, x3, x4)
return B.out
if k <= 0: A.out = x4 + x5
else: B()
return A.out
print A(10, 1, -1, -1, 1, 0);
# correct output is -67
The scope of k remains one problem, as it is passed as an argument to
A.
I think x1,x2,x3,x4 are meant to be lambdas as well... :-)
