Detect Circular Pattern Match

Code

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

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

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