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

    uint16_t copy;

    for(int i=0;i<16;i++){

        copy = reg;

        copy = (copy << i) | (copy >> (16-i));

        if(copy == target){

            return 1;

        }
    }

    
    return 0;
}

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