33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    uint8_t n = 0;
    while(n<16){
        uint16_t reg_s = (reg << n) | (reg >> (16-n));
        if(reg_s == target ) {
            return 1;
            break;
        }
        n++;
    }
    return 0;

}

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