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

    for(int i = 0; i < 16; i++) {
        if (target == reg) return 1;
        uint8_t num = reg & 0x1;
        reg >>= 1;
        reg += (num << 15);
    }
    return 0;
}

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