33. Detect Circular Pattern Match

#include <stdio.h>
#include <stdint.h>

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    int i=0;
    while(i<16)
    {
        if(reg&(1<<0)){
            reg=reg>>1;
            reg|=(1<<15);
        }
        else reg=reg>>1;

        if(reg==target)return 1;

        i++;
    }
    return 0;
}

int main() {
    uint16_t reg, target;
    scanf("%hu %hu", &reg, &target);
    printf("%hhu", is_circular_match(reg, target));
    return 0;
}
