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
    int dem =0;
    for(int i=0; i<16; i++)
    {
        reg = (reg >> (16-i)) | (reg << i);
        if(reg == target ) 
        {
            dem =1;
            break;
        }
    }
    
    return dem;
}

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