Detect Circular Pattern Match

Code

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    for(uint16_t i = 0; i < 16; i++){
        uint16_t possible1 = (reg << i) | (reg >> (16-i));
        uint16_t possible2 = (reg >> i) | (reg << (16-i));
        if ((target == possible1)||(target == possible2)){
            return 1;
        }
    }
    return 0;
}

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