Question

Quiz 1, number 3, the double recursion program. I am having a tough time seeing what should be printed. Is there a way to analyze this with a chart?

Answer 1

can we see the code?

Answer 2

def f(s):
if len(s) <= 1:
return s
return f(f(s[1:])) + s[0] #Note double recursion

print f('mat')
print f('math')

Answer 3

For some reason, the spaces I insert are not being displayed...

Answer 4

i do not see any inserted spaces in your code though...
