Let's see how many of us can use programming skill outside in real world.

Pair socks from a pile efficiently?

Wear Odd Socks!

Pick random socks

Only buy plain black socks of the same kind... the OddSockError no longer occurs.

If it's be me will make it null, don't wear any so you don't have a tension of sorting.

@RamChandra But then surely when trying to call any sock related method you would have a NullRef and have to deal with null propagation.

@ridecar2 thinking about that situation, maybe creating a new object shoes with socks declared as final so you don't have to pick one.

Foreach (Sock sock in socks)
{
If (sock.pattern.hasMatch(patternArray))
{
int pair = patternArray.Match(sock);
patterArray.moveToDrawer[pair]
}
else
{
patternArray.Add(sock)
}
}

1: yes, there is a function for "hasMatching"

2: yes, it could be more efficient, but this way its a more accurate representation of how I actually sort socks.

3: why would you wear odd socks? That's just annoying.

Quantum bogo sort! (Like I'd care if I have matching socks :P)

@monr0e No one sees them anyway ¯\_(ツ)_/¯

Im colorblind so any 2 socks is a pair :^)

Sleepsort by hash of pattern. Human won't act faster than that anyway..^^

But if you want it efficient, call

function getSock() {
const i = Math.floor(Math.random() * socks.length);
return socks.splice(i, 1)[0];
}

Twice.😋
