Day 4 - use types

[narimiran]

I've seen your Day 4 solution and your (return) types are quite verbose/unreadable. This can be remedied by defining the types and then using their name.

Something like this:

type
  Day = tuple[name: string, times: seq[int]]
  Days = seq[Day]
  Minutes = array[60, string]
  GuardPattern = tuple[date, id: string]
  Sleepiest = tuple[total, guard, mostMinute: int]
  MostMinutes = tuple[totalCount, current: int]


proc parseInput(input:string): (Table[GuardPattern, Minutes], Days) =
  var table = initTable[GuardPattern, Minutes]()
  # etc.


proc findGuardThatSleepsMost(days: Days): Sleepiest =
  var sleepyHead = ""
  let guard = days.map(func(day: Day): string = day[0])
    .deduplicate()
    .map(func(guard: string): Sleepiest =
      let totalMinutes = days
        .filter(func(day: Day): bool = day[0] == guard)
        .map(func(d: Day): seq[int] = d[1])
        .foldl(a.concat(b))
  # etc.

I hadn't learn about types in day 4 :D Now i use them. We'll see if I get the time to go back and revisit the problem of day 4
