Detect Circular Pattern Match

Code

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    for (int i=0; i<16; i++){
        uint16_t testLeft= ((reg<<i) | (reg>>(16-i)));
        uint16_t testRight = ((reg>>i)|(reg<<(16-i)));
        if ((target == testLeft)||(target == testRight)) return 1;
    }
    return 0;
}

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