S

Output

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

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>

int main()
{
	char S[3];
	int rep;
	
	S[0] = '0';
	S[1] = '0';
	S[2] = '0';
	
	scanf("%s", S);
	
	if (S[2] == 0)
	{
		printf("%c%c", S[0],S[1]);
	}
	
	else
	{
		printf ("%c%c%c", S[2], S[1], S[0]);
	}
	
	return 0;
