>Advent of Code is a series of small programming puzzles for a variety of skill levels. They are self-contained and are just as appropriate for an expert who wants to stay sharp as they are for a beginner who is just learning to code. Each puzzle calls upon different skills and has two parts that build on a theme.

You should put SICP in the picture.

Swift

func partOne(_ input: [String]) -> Int {
return input.map { Int(String($0)) ?? 0 }.reduce(0, +)
}

print(partOne(input))

func partTwo(_ input: [String]) {
let inputFixed = input.map { Int(String($0)) ?? 0 }
var already_seen = Set()
var freq = 0
var found_repeat = false
while !found_repeat {
for val in inputFixed {
freq += val
let (insertWasSuccessful, insertedValue) = already_seen.insert(freq)
if !insertWasSuccessful {
print(insertedValue)
found_repeat = !insertWasSuccessful
break
}
}
}
}

partTwo(input)

You should choke on a dick.

>mixing camel case and snake case
That's what I get for "porting" my C++ solution I guess.

Nah, algos book much more represents the current situation.

sorry :c

public long Duplicate()
{
while (true)
{
foreach (var n in _input)
{
_curfreq += n;
if (!_seen.Add(_curfreq))
{
return _curfreq;
}
}
}
}

I made it work though :)
