So I need to write a function based off of nCr, which I have here:
def choices(n, k):
if n == k:
return 1
if k == 1:
return n
if k == 0:
return 1
return choices(n - 1, k) + choices(n - 1, k - 1)
It works fine, but then I need to add in so that the user can have an input box
for n and k.
def choices(n, k):
if k == 1:
return n
if n == k:
return 1
if k == 0:
return 1
return choices(n - 1, k) + choices(n - 1, k - 1)
n_input = int(input("Number of courses you like: "))
k_input = int(input("Number of courses you can register for: "))
The above doesn't return any value at all. And then I need it to print the
total number of ways of choosing k out of n courses, which I only have:
print ("Total number of ways of choosing %d out of %d courses: " % (n_input,
k_input))
So basically I need help figuring out why it won't return any value and how to
print that final value.
Actually calling choices with n_input and k_input as inputs might help
your cause.
