Detect Circular Pattern Match

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

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

  
}

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