Detect Circular Pattern Match

#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++)
    {
        if(((extended >> i) & 0xFFFF) == target)
            return 1;
    }


    return 0;
}

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