Detect Circular Pattern Match

Code

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
   if (reg==target){
    return 1;
   }

   for (int i=0; i<15;i++){
    reg = (reg>>1)|(reg<<15);
    if (reg==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;
}
