Numbers of Armstong WP34s

[Thomas Klemm]

There's another online tool to visualize Python.
Just copy this:

Code:

def armstrong(n, i, a, b):
    if i == 0:
        if a == b:
            print a
    else:
        for d in range(10):
            armstrong(n, i-1, 10*a + d, b + d**n)

armstrong(3, 3, 0, 0)

Paste it into the text-box and press [Visualize Execution].
Now you can step [Forward >] and [< Back] through the program just as you are used to from your calculators. However stepping back will undo the operation.

Cheers
