Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
In your code, at each iteration, if a character is found in a str1, a new string is created. It turns out that in the worst case you will get str1.length rows in memory
duplicate issue (see @donaldsebleung's issue below)
Read any of the many posts asking the same: 1 is already there, so it can't be used.
The answer to this should be 1 as 00 is invalid but test requires it to be 2 why is that?

Not an issue ;-)
how the heck do they need more 2 letters to depict 120 elements, well i guess thats happens when you let non CS guys name things.
There... no bitwise ;)
lul, cant figure it out ?
Bitwise feels like cheating but I'm still technically not using "&&" and "||"!
Added tests and made the classes static/public and now runs
Yes, why not;-)... here it looks like "5 & (52-51)"... or perhaps "5 & (52---51)":-)
