Leet to English Translation

Javascript (49 + 5635) * 10 / 2174 = 26.14

Online Demo:

"Real dictionary" option doesnt work on drop box but it will work if run in a real web server. Tested in visual studio development server and google chrome.

Score:

49 leet items = 49

Capitalization bonus = 5 * 49 = 245

dictionary lookup bonus = 20 * 49 = 980

exclamation bonus * 3 = 90 * 49 = 4410

When the program is compiled to a file named min-lt, you can write the following shell script

#!/bin/bash
./min-lt "|-|3 15 $|_|(# @ n00b"
./min-lt "\$#!+"
./min-lt "\/\/ 1 |< 1 P 3 [) 1 A"
