Detect Circular Pattern Match

Code

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    for(int i = 1; i <= 16; i++){
        uint16_t test = 0;
        uint8_t ans = 0;
        test = (reg << i) | (reg >> (sizeof(reg) * 8 - i));
        ans = (test == target)? 1 : 0;
        if(ans == 1){
            return ans;
        }
    }
    return 0;
}

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