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 d=((uint16_t)reg<<16)|reg;
    for(int i=0;i<16;i++){
        uint16_t r=(d>>i)&0xffff;
        if(r==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;
}
