PRS三个字母换成2进制，取后三位刚好是023，以此为索引打表(3表示平局，2表示赢，1表示输)

main() {
    char s[80], t[80], *p, *q, c, m[] = "3321333313322313";
    int x[3];
    while (gets(s) && *s != 69) {
        gets(t);
        p = s;
        q = t;
        *x = x[1] = 0;
        while (c = *p++)x[m[(c & 3) * 4 + (*q++ & 3)] - 49]++;
        printf("P1: %d\nP2: %d\n", x[1], *x);
    }
}
