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 output = 0;
    for (int n=0; n<=16; n++){

        reg = (reg << n)| (reg >> 16-n);

        if (reg == target){

            output=1;
        }
    }


    return output;
}

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