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 n = 0;
    int ret = 0;

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

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


        if(reg == 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;
}
