33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    
    uint16_t mask = target;

    for(int i = 0 ; i < 16 ; i++)
    {   
        if(reg == target)
            return 1;

        if((target & 1) == 1)
        {
            target >>= 1;
            target |= (1 << 15);
        }
        else
            target >>= 1;
    }
    return 0;
}

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