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
    uint8_t n = 0;
    while(n<16)
    {
        reg = ((reg << 1) | (reg >> 15));
        if(reg == target)
            break;
        n++;
    }
    return (n != 16);
}

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