题解：

func originalDigits(s string) string {
    c := map[rune]int{}
    for _, ch := range s {
        c[ch]++
    }

    cnt := [10]int{}
    cnt[0] = c['z']
    cnt[2] = c['w']
    cnt[4] = c['u']
    cnt[6] = c['x']
    cnt[8] = c['g']

    cnt[3] = c['h'] - cnt[8]
    cnt[5] = c['f'] - cnt[4]
    cnt[7] = c['s'] - cnt[6]

    cnt[1] = c['o'] - cnt[0] - cnt[2] - cnt[4]

    cnt[9] = c['i'] - cnt[5] - cnt[6] - cnt[8]

    ans := []byte{}
    for i, c := range cnt {
        ans = append(ans, bytes.Repeat([]byte{byte('0' + i)}, c)...)
    }
    return string(ans)
}
