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 Return = 0;
    for (uint8_t Index = 1; Index < 16; Index++)
    {
        if ( reg == target )
        {
            Return = 1;
            break;
        }
        reg = (reg << Index) | ( reg >> (16-Index));
    }
    return Return;
}

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