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
    //uint8_t ret=0x00;
    uint8_t count=0;
    while(count<16)
    {
        if(reg==target)
        return 1;
        else
        {
            //int ret=reg>>15;
            int ret=reg<<1|reg>>15;
            reg=ret;
        }
        count+=1;
    }
    return 0;
}

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