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 i =0;
    uint8_t output = 0;
    while((reg != target) & (reg !=0) & (target !=0)){
        i++;
        reg = (reg << i) | (reg >> (16-i));
        if(target == reg) output = 1;
        else output =0;
    }
    return output;
}

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