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
    uint8_t match = 0;
    // Check the left rotation first (apparently enough)
    // for (uint16_t i = 0; i<16 ; i++){
    // uint16_t tmp = (reg << i) | (reg >> (16 - i));
    // if (tmp == target){
    //      match = 1;
    //      break;
    // }
    // }
    // Case with right rotation as well: 
    for (uint16_t i = 0; i<16 ; i++){
    uint16_t tmp = (reg >> i) | (reg << (16 - i));
    if (tmp == target){
         match = 1;
         break;
    }
    }
    return match;
}

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