Detect Circular Pattern Match

Code

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    int i;
    for(i = 0 ; i<16;i++)
    {
       if(reg == target) return 1;
       reg = (reg <<1) | (reg >>15);
    }
    // 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;
}
