Kata

Many of you, happy & honest codewarriors, are probably wondering the same thing looking at the CW leaderboard:

• How can someone gain so many points (more than 30000) in CW?
• How can someone publish dozens of new kata a day?
• How can someone speak chinese (uh, no, not that question, shame on you !)
• How can...

Ok, ok, ok! We get the picture! The answer is very simple:

Most of these "warriors" are aliens from the 5th dimension, come to earth to torment the poor humans

The good news is: we can examine their names to find who they really are.

Your Task :

You may code a checkUser/check_user function to check a userName/user_name to see who he/she is. The algorithm is:

1.) "Un-leet" the name; replace 0123456789 with olzeasbtBg respectively (e.g. replace 0 with "o", 6 with "b", 2 with "z". . .)

2.) Get the "binary" value of the name, by taking the name of the Imp of Imps himself, Mxyzptlk, and replacing each letter in his name with a 1 if it is present in user's name, and a 0 if it's not (ignore case)

3.) Compute the 5th dimension level by dividing the decimal value of "bin"-value by 255 and multiplying by 100:

fifthDimensionLevel = 100 * parseInt(binaryValue, 2) / 255

fifth_dimension_level = 100.0 * binary_value.to_i(2) / 255.0

4.) Finally, depending of this final score, return a comment:

  score : comment to be returned
--------+------------------------------------------------------------------------------
 <  1   : "This one's too clean, should be a bot."
 <  50  : "This one seems ok, may be there's still some humans around here..."
 <  90  : "This one's probably an alien from 5th dim, be careful!"
 >= 90  : "Yeeerk!!! Mr Mxyztplk himself the imp of imps! Only Superman can beat him!"

These messages are preloaded in an array MSGS

Example:

name : 'Am4b0'
1. unleet --> 'Amabo'
2. bin-value: 'Mxyzptlk' -> '10000000' (only the 'M' matches Amabo)
3. level: `10000000` to decimal -> 128, 100*128/255 -> ~ 50.19607843137255
4. msg: "This one's probably an alien from 5th dim, be careful!" (==MSGS[2] )
