Check if at least two out of three booleans are true

Question

An interviewer recently asked me this question: given three boolean variables, a, b, and c, return true if at least two out of the three are true.

My solution follow

Answer 1

The most obvious set of improvements are:

// There is no point in an else if you already returned.
boolean atLeastTwo(boolean a, boolean b, boolean c) {
    if ((a && b) || (b && c) || (a && c)) {
        return true;
    }
    return false;
}

and then

// There is no point in an if(true) return true otherwise return false.
boolean atLeastTwo(boolean a, boolean b, boolean c) {
    return ((a && b) || (b && c) || (a && c));
}

But those improvements are minor.
