Is this solvable? I am finding it mathematically impossible to find a variable x that satisfies the equation x & 111100 == 011101. I could have done something wrong since I am using C# instead of javascript but wanted to make sure this was solvable before spending any more time on it.

i'm not sure what your equation refers to (and does seem unsolvable), but this problem is definitely solvable and has been solved by multiple people.

good luck,

It was a problem with the NaN function, I interpreted it as checking to see if the character is a number from 0-9 (doh)

I done it complete without any programming...

the only thing you must du is to try each char by char as long
as the right letters are printed....

I done it within 30min by hand

And don't mix 1 and l up ... Took me ages to find this mistake

i think writing a script for this takes longer, than doing it by hand. the first few characters are just guessing but after this, google may be your friend

(again)

i'm surprised none of you smart guys recognizes what the function actually does...
it's ridiculous writing [more than] a line of script or even picking up a pen.

to know the function didn't help me at all
i think thr function behave strange for "unnormal" input like space, comma etc
but maybe i'm trying to type in the wrong word

Agree 100%

Supar eazy if you've been exposed to the output from wrong answers before...

'^.*=+$' for the win

i reversed the algortihm in c++ and found the solution. but the output is wrong in 2 letters. instead of <'> it prints %27 and instead of space it prints %20. Then i realized that this is a web script so it uses url encoding, so i replaced these 2 characters with the appropriate ones and it was over

why does ((enc2 & 15) << 4) works ,but (enc2 << 4) not??

I used python for this challenge.
After done at all, I think I can solve it by hand :lol

The encoding is "obviously" -- it is standard -- it can returned with a free accessable OnlineTool==
