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 i = 16;
    while(i >= 0){
    uint16_t a = 1 & reg;
    reg = (reg >> 1) | (a << 15);
    if(reg == target)
    return 1;
    i--;
}
    return 0;
}

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