still why do the methods have to be private

Truly a Java solution of all time

my man can't let others have fun

Somehow I got through this,

Wonder how to get away with making a puzzle task, if we just throw a (or some) random logic and hide it behind the test.

Don't hate the player - hate the game

there are some few more cases that equals 9: 4806,4820-29, 4833

"ONE(?) or more consecutive groups of zeros can be eliminated" - this is confusing, if we trying "return the same address reformatted to the shortest possible length", but the actual requirement is not eliminating one group of zeroes ("a single group of zero should be left as-is"), we need better instruction

So "contraction" also means expanding in this problem

Input

2a03:2880:2130:cf05:face:b00c::1

Expected:

2a03:2880:2130:cf05:face:b00c:0:1

Then just remove everything other than brackets first

this is what a true Java solution feels like (I don't even want to read all this)

how is "the guide that tell us to do everything" actually making the task at least 5 times difficult than the original task

I have completed this, and still want this one to be permantly deleted

This is actually an issue because I didn't know what the hell fizzbuzz is

This one is bad, because it invole division into decimal, so it takes my solution 20 tries to submit due to decimal precision

Not a fancy solution as others, but still...

Any anti-regex extremist that passed this problems should be awarded twice the points

target number is too big sometime, made it through 2nd try, guess I'm just lucky

the String u: find the digit at the end of str and plus 1 to it, else no change to string

return: check if the string has a digit -> then return it as is or plus 1

technically the return could be better written like this

return u==str?u+1:u;

pass with this test : findSolutions(["moa", "moe", "moi", "moo", "mou", "mua"])
