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 result;
    for (int i = 0; i <= 15; i++) {
        result = (reg >> i) | (reg << (16-i));
        result &= 0xffff;

        if (result == target) {
            return 1;
        } 
    } return 0;
}

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