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
    int n =15;
    while (n!=0){
 uint16_t left_cir_match = reg <<n | reg >>(16-n);
 uint16_t rig_cir_match = reg >>n |reg <<(16-n);
   if(left_cir_match==target || rig_cir_match == target)
    return 1;
  n--;
    }
   

    return 0;
}

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