Detect Circular Pattern Match

Code

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

uint8_t leftCheck(uint16_t reg, uint16_t target)
{
    for(uint8_t x=1; x<=15;x++)
    {
        if((reg^target) == 0) return 1;
        uint16_t cap_bit = reg & 0x8000;
        cap_bit>>= 15;
        reg<<= 1;
        reg|= cap_bit;
    }
    return 0;
}

uint8_t rightCheck(uint16_t reg, uint16_t target)
{
    for(uint8_t x=1; x<=15;x++)
    {
        if((reg^target) == 0) return 1;
        uint16_t cap_bit = reg & 0x01;
        cap_bit<<= 15;
        reg>>= 1;
        reg|= cap_bit;
    }
    return 0;
}

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    if(leftCheck(reg, target))  return 1;
    else    return(rightCheck(reg,target));
}

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