Every permutation of the alphabet up to 29 characters?

Question

I\'m attempting to write a program that will generate a text file with every possible permutation of the alphabet from one character up to twenty-nine characters. I\'ve chosen 2

Answer 1

Even if you could store this on disk, like thirydot pointed out, you'd run out of time doing this.

Just generating (and not storing) all the 6-letter possiblilies took 24 seconds on my computer:

$ time perl letters.pl

real    0m24.837s
user    0m24.765s
sys     0m0.030s

Which is 7.7X10^-8s per word, That means it would take 8.4x10^33s or 2.6x10^26 years to do this.

You need to think more about your algorithm.
