Hey all,

Here's the following algorithm:

int encryption(int a, int b) {
    short int c, c2;
    uint8_t d;

    c = a ^ b;
    c2 = c;

    d = 0;
    while(c) {
        c &= c - 1;
        d++;
    }

    return d;
}

How can I find which variable a and b I should send in that function to decide of the output value of d?

In other words, how can I reverse the algoritm to let's say if I want d=11?
