33. Detect Circular Pattern Match

#include <stdint.h>

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    uint8_t n = 16;
    uint8_t bitValue = 0;

    if(reg == target)
    {
        return 1;
    }
    while(n > 0)
    {
        bitValue = (reg & 0x8000) >> 15;
        reg = reg << 1;
        reg = reg | bitValue;
        if(reg ==  target)
        {
            return 1;
        }
        n--;

    }
    // 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;
