import java.util.Scanner; public class Main{ public static void main(String[] args){ Scanner sc = new Scanner(System.in); while(sc.hasNextLine()){ String str = sc.nextLine(); String rts = ""; for(int i = str.length()-1;i >= 0;i--){ rts += str.substring(i,i+1); } System.out.println(rts); } } }
倒序逐个截取字符即可
