We got 16 solutions this weekend, written in 6 languages:
1 solution in C++
1 solution in AWK
1 solution in Basic
2 solutions in C
2 solutions in Lua
9 solutions in Python
The solutions are uploaded on GitHUb, in the readme are my comments https://github.com/OLIMEX/WPC/tree/master/ISSUE-3
There are several very small and compact solutions made in Python, well done!
Solution-16 approach is to work first with numbers (based on the ASCII code) than to compare strings, but does this improve the speed?
