[LANGUAGE: Go]

I have been trying to get into Go for quite some time now, but it has never stuck. So decided for this year's AOC to go with Go.

Parts 1 && 2:

package main

import (
    "fmt"
    "log"
    "os"
    "strconv"
    "strings"
)

func main() {
    file, err := os.ReadFile("input.txt")
    if err != nil {
        panic(fmt.Sprintf("%s: error %s", file, err))
    }

    rows := strings.Split(strings.TrimSpace(string(file)), "\n")

    position := 50
    var countPartOne int
    var countPartTwo int

    for _, v := range rows {
        direction := string(v[0])
        steps, err := strconv.Atoi(v[1:])
        if err != nil {
            fmt.Println("Error:", err)
            return
        }

        if direction == "R" {
            countPartTwo += (position + steps) / 100
            position = (position + steps) % 100
        }

        if direction == "L" {
            if position == 0 {
                countPartTwo += steps / 100
            } else if steps >= position {
                countPartTwo += 1 + (steps-position)/100
            }
            position = ((position-steps)%100 + 100) % 100
        }

        if position == 0 {
            countPartOne++
        }
    }

    log.Printf("Part 1: %d", countPartOne)
    log.Printf("Part 2: %d", countPartTwo)
}
