33. Detect Circular Pattern Match

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
     uint16_t left_buff=0;

    for(int i=0;i<16;i++)
    {
        left_buff=(reg<<i)|(reg >> (16 - i)) & 0xFFFF;;
        right_buff=(reg>>i) | (reg << (16 - i)) & 0xFFFF;; 

        if((left_buff==target)||(right_buff==target)){
            return 1;

        }

    }
    return 0;
}

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