[This is for Javascript]
Can I get some help here? It keeps failing on random test cases, I think my result is right.
If not, could i get an explanation? Because even in my head - if i manually try and do it, that's how it should be.
E.g
Battlefield: rbpl[l]#m[cwd]bzu[pvx]###[tq]on expected 'l' to equal 'lcwd'

Battlefield breakdown:
rbpl[l]#m[cwd]bzu[pvx]###[tq]on
[l]#[cwd][pvx]###[tq]
[l]#[cwd][pvx]###[tq]
[l cwd ][pvx]###[tq]
[l cwd ][pvx##tq]
[l cwd ]pvx#tq
l

Likewise, as someone else in the comment section - I ran this:
Testing for [flrxgj][eyadcb]s#sgryedufaxwzegqeezrjcirqaoce#dcaigasncuemtphwijoyuroa[gdlmvrsj]pacjkssikw Expected: "flrxgjeyadcbgdlmvrsj", instead got: "flrxgj"

Additional Random Tests:
Battlefield: nqt[pav]d#[k]pu[qv]#[vyp]#d[dw]##
[pav]#[k][qv]#[vyp]#[dw]##
[pav]#[k][qv]#[vyp]#[dw]##
[pavk][qv]#[vyp]#[dw]##
[pavk][qvvyp]#[dw]##
[pavk][qvvypdw]##
[pavk][qvvypdw#`

expected 'pavk' to equal 'pavkqv'

Correct, it should be
[ '1/2',
'1/7',
'1/59',
'1/5163',
'1/53307975',
'1/9007199254740992' ]

Above is wrong because javascript makes issues in its math calculation. Best to round each of your answers then do calculation.

Idk you are definitely getting better cause i struggled big time with this. But mainly because I went through so many different solutions, wasting time and stuff; the trick here was i expected everything to be sorted.
In the end, pulled out the good ol' sort algorithms, and finished it in 30mins. I should say my solutions are always super unique to everyone elses.

This felt harder than any problems i solved so far :x - and i did some 4kyu problems.
But was hella fun!
Great kata

wow this eloquent coding completely destroys my trash behemoth of a code. (;´༎ຶٹ༎ຶ`)

well.. this was way easier than i made it ought to be initially.
Some other people's solutions though, doing in a liner -
I want to do that one day
