#include <stdio.h>

int main()
{
    int a, b, c;
    scanf("%d%d%d", &a, &b, &c);
    if(a-b == 0) printf("S\n");
    else if(a-c == 0) printf("S\n");
    else if(b-c == 0) printf("S\n");
    else if((a+b)-c == 0) printf("S\n");
    else if((b+c)-a == 0) printf("S\n");
    else if((a+c)-b == 0) printf("S\n");
    else printf("N\n");
    return 0;
}
