Detect Circular Pattern Match

Code

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    for(uint8_t i = 0u; i < 16u; i++){
        if (reg == target)
            return 1;
        reg = (uint16_t)((reg << 1u)|(reg >>15u));
    }
    return 0;
}

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