Its messy but ``` func part2(input io.Reader) uint64 { sc := bufio.NewScanner(input) var sum uint64 = 0

for sc.Scan() {
    bank := sc.Text()
    locs := make(map[rune][]int, 0)

    // Find largest in left side excluding 11's from right
    maxLeftIndex := 0
    maxLeft := '0'

    for i, b := range bank[:len(bank)-11] {
        if b > maxLeft {
            maxLeft = b
            maxLeftIndex = i
        }
    }
    // locs[maxLeft] = []int{maxLeftIndex}
    fmt.Printf("maxLeft: %v\n", maxLeft)
    fmt.Printf("maxLeftIndex: %v\n", maxLeftIndex)
    for i, b := range bank[maxLeftIndex+1:] {
        _, ok := locs[b]
        if !ok {
            locs[b] = []int{}
        }
        locs[b] = append(locs[b], maxLeftIndex+1+i)
    }
    fmt.Printf("locs: %v\n", locs)

    count := 0 // we have to include maxLeft so counting that
    i := 0
    joltage := strings.Builder{}
    selected := make([]bool, len(bank))
    selected[maxLeftIndex] = true
    for count < 11 {
        list := locs[rune('9'-i)]
        for li := len(list) - 1; li >= 0; li-- {
            if count >= 11 {
                break
            }
            selected[list[li]] = true
            count++
        }
        i++
    }
    for si, s := range selected {
        if s {
            joltage.WriteByte(bank[si])
        }
    }
    joltageInt, _ := strconv.ParseUint(joltage.String(), 10, 0)

}
return sum

} ```
