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 reg1 = reg;
    uint8_t pos = 1;
    reg = (reg << pos) | (reg >>(16 - pos));
    while(pos <= 16)
    {
        if(reg == target)
        {
            return 1;
        }
        else
        {
            pos = pos + 1;
            reg = (reg << pos) | (reg >>(16 - pos));
        }
    }
    return 0;
}

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