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
    int count1, count2 = 0;
    while(reg)
    {
        count1 += (reg & 1);
        reg >>= 1;
    }

    while(target)
    {
        count2 += (target & 1);
        target >>= 1;
    }

    if(count1 == count2)
        return 1;

    return 0;
}

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