33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    uint8_t bit_extraction;
     
    for(int i = 0; i < 16; i++){

        bit_extraction = (reg >> 15) & 1; 
        reg = (reg << 1) | bit_extraction;

        if(reg == target){
            return 1;
        }
    }
    
    return 0;
}

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