33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    uint16_t n = 0;
    uint16_t test = (uint16_t)((target << n) | (target >> (16 - n)));
    while ((0 != (test^reg)) && (n <= 15))
    {
        test = (uint16_t)((target << n) | (target >> (16 - n)));
        n++;
    }
    if(n <= 15)
    {
        return 1;
    }
    else
    {
    return 0;
    }

}

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