# Obfuscated Hello World

Create the shortest possible obfuscated program that displays the text "Hello World".

In order to be considered an obfuscated program, it must meet at least two of the following requirements:

• Does not contain the characters: h, l, w and d in any case
• Does not contain the characters: e, o, r, 0, and 1 in any case
• Does not contain the characters: 2 or 7

Input:
none

Output:
Hello World

• I guess import in python is not permitted. – Alexandru Feb 1 '11 at 0:07
• Does these rules apply to language keywords as well? – hallvabo Feb 1 '11 at 13:04
• are those case insensitive restrictions? – oenone Aug 4 '11 at 14:22
• Could someone explain why 2 and 7 are not allowed? I'm just curious as I don't see why those were chosen in particular. – Thomas Eding Aug 5 '11 at 23:01
• @trinithis, and others, ASCII character 72 is "H" which is why I chose those two – Kevin Brown Sep 18 '11 at 23:18

# Gol><>, 21 bytes

"mu{x)xuunQ"T:Z;9-ot


This is a program that JoKing made, golfing the heck out of it.

This is a really simple, not very creative way of doing this, all it does is just encode everything 2 below their actual ascii encoding, the hardest part is not using 'l', which in gol><> is the length of the stack!

# Python 3, 85 bytes

Not golfed, but obfuscated.

input(('%c'*11)%(9*8,93+8,99+9,9+99,3999//36,4*8,9*9+6,3996//36,4353//38,36*3,5*4*5))

• From a golfing standpoint, the fact that you're already using 11 to break rule 2 means that every code point except 72, 32, and 87 are valid (since 0 will also be allowed). From an obfuscation standpoint, I'm sure there are more creative and fun numbers you can use, like idk, 33**3//399-3 for 87, 3225%346 for 111, etc. – Value Ink Jun 7 at 21:45

## (K+R)eg, 16 bytes

1 byte shorter than the accepted solution (GolfScript).

Jgnnq\"Yqtnf(;;'

This encodes the string by adding all characters by 2.
