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=0;i<16;i++){
        uint16_t result = (target << i) | (target >> (16 - i));
        if(result == reg) return 1;
    }
    return 0;
}
int main() {
    uint16_t reg, target;
    scanf("%hu %hu", &reg, &target);
    printf("%hhu", is_circular_match(reg, target));
    return 0;
}
