Solution

My Solution

func minimumLength(s string) int {
    if len(s) < 3 {
        return len(s)
    }

    m := [26]int{}

    for _, c := range s {
        m[c-'a']++
    }

    sum := 0
    for _, val := range m {
        if val == 0 {
            continue
        }
        if val&1 == 1 {
            sum += 1
        } else {
            sum += 2
        }
    }

    return sum
}
