Very Silly One Liner....

[John Carter]

Here is my very very silly one liner for the day....

ruby -e '100.times{|n| a,b=n.divmod 10;10.times{|c|;d=c*10+a;next unless
d!=0&&n%d==0&&b==c*n/d;printf "%02d/%02d=%d\n",n,d,n/d}}'

Carter's Clarification of Murphy's Law.

"Things only ever go right so that they may go more spectacularly wrong later."

From this principle, all of life and physics may be deduced.

Took me a good minute to figure out what you were doing there Cute,
though I submit that
n/d = 10 and n/d = 1 are artistically unsatisfying, particularly the
former. Plus you miss a nice case...

ruby -rrational -e '100.times{|n| a,b=n.divmod
10;10.times{|c|d=c*10+a;next unless (n!=d) && (b*d!=0) &&
(b*d==c*n);printf "%02d/%02d=#{Rational(n,d)}\n",n,d}}'
