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
    uint32_t extended = (uint32_t) reg << 16 | reg;
    for (int i =0; i <16; i++){
        uint16_t rotated = (extended >> i) & 0xFFFF;
        if (rotated == target){
            return true;
        }
    }
    return false;
}

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