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
    int i = 0;
    while (i < 16) {
        if (((uint16_t)(reg << i) | (uint16_t)(reg >> (16 - i))) == target){
            return 1;
        }
        i ++;
    }
    return 0;
}

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