golang 版本

package main

import (
    "fmt"
)

func main() {
    a := ""

    n, _ := fmt.Scan(&a)
    if n == 0 {
        return
    } else {
        res := ""
        for i := len(a) - 1; i > -1; i-- {
            res += fmt.Sprintf("%c", a[i])
        }
        fmt.Println(res)
    }
}

python版本

scan = input()

res = ""
for i in range(len(scan) -1, -1, -1):
    res += scan[i]

print(res)
