Discussion/Puzzle Questions for Week 5:

Here are two cryptograms for you to solve.
One is a simple substitution cypher, the other
is a simple columnar transposition cypher
(but I'm not saying which is which).
The texts are both in English; in fact, each is
a paragraph extracted from the textbook (with 
punctuation removed).

Cypher 1:

Cypher 2:

These cyphers are not too hard to decode,
given a little time, a computer, and a 
friendly programming language.  If you 
like puzzles, please give them a go. If you
don't (try to) solve them, at least be prepared
to describe some simple computer programs 
that would be useful to help a human solve
them, or even to solve them almost automatically.
