33. Detect Circular Pattern Match

#include <stdio.h>
#include <stdint.h>


uint8_t is_circular_match(uint16_t reg, uint16_t target)
{
    uint32_t dummy=((uint32_t)reg << 16) | reg;
    uint16_t rotated; 
    for(int i=0;i<16;i++)
    {
       rotated= (dummy >> i) &0xFFFF;
        if(rotated==target)
        {
            return 1;
        }
    }
    // Your code here
    return 0;
}

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