    in python -

    def bitwiseAnd(N, K): if K - 1 | K <= N: return K -1 else: return K-2

    any one explain why this code works always int bitwiseAnd(int n, int k) { if (((k - 1) | k) <= n) { return k - 1; } else { return k - 2; } }

    public static int bitwiseAnd(int N, int K) {
    return ((K - 1) | K) <= N ? K -1 : K -2;
}

    PYTHON 3 SOLUTION

    python:

        def bitwiseAnd(N, K):
        if K - 1 | K <= N:
                return K -1
        return K-2

    JavaScript/TypeScript

    function bitwiseAnd(N: number, K: number): number {
    let max = 0;
    let aANDb;

    for (let a = 1; a < N; a++) {
        for (let b = a + 1; b <= N; b++) {
            aANDb = a & b;
            if ((aANDb) < K && (aANDb) > max) {
                max = aANDb;
            }
        }
    }

    return max;
}
