Detect Circular Pattern Match

Code

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

uint16_t circular_bit_shift(uint16_t reg, uint8_t n)
{
   n%=16;
   return(reg>>n)|(reg<<(16-n));
}
uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    for (uint8_t i = 0;i<16;i++)
    {
        if (reg==target)
        {
           return 1;
        }
        reg=circular_bit_shift(reg, 1);
    }
    return 0;
}


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