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 left_shift, right_shift;
    for(int i=0;i<16;i++)
    {
    left_shift = reg <<i & 0xFFFF;
    right_shift = reg >> (16-i);
    reg = left_shift |right_shift;
    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;
}
