ADDED Double sorry! I didn't realize I could go bask and modify my posts.

Really cool!

Sorry, didn't realize I needed tags...

Benchmark: timing 1000000 iterations of Grep, Max, Ternary...

Grep: 4 wallclock secs ( 3.61 usr + 0.01 sys = 3.62 CPU)

Max: 9 wallclock secs ( 8.47 usr + -0.01 sys = 8.46 CPU)

Ternary: 9 wallclock secs ( 8.51 usr + 0.02 sys = 8.53 CPU)

This is perl, version 5.005_03 built for i386-linux

Linux 2.2.12-20

P3 450MHz
