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 rotated = ((target<<i) | (target>>(16-i)));
        if (rotated == 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;
}
