S

Output

If the length of S is 2, print S as is; if the length is 3, print S after reversing it.

Sample Input 1

abc

#include <iostream>
using namespace std;
int main(void){
    char s[10];
	cin>>s;
	int a=0;
	for(int i=0;s[i]!=NULL;i++)
	{
	a++;
	}
	if(a==2){cout<<s[0]<<s[1]<<endl;}
	else if(a==3){cout<<s[2]<<s[1]<<s[0]<<endl;}
	
    return 0;
}
