Really good kata for practice! Not really tough but needs patience and determination！

java 11 .
expected:<[6.21.181.189]> but was:<[48.86.107.61]>
This is one of the test and below are each number's bits [6.21.181.189].
110
10101
10110101
10111101
I don't know how i can count 3+5+8*2 = 32 if my brain is not washed...

I really don't undersand it said the IPv4 is 32 bits that's pretty clear and the random tests are not 32 bits lol so weird.I have no idea how to solve,someone can answer my question?Appreciate so much.

sort is pretty kind of simplest way but costs too much because it takes O(nlog(n)) for fastest merge sort,but at least,it looks pretty clear and readable,well done!Arr
