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)
}
