// # Sample
// Bitwise Operators
//
// # Description
// Bitwise operators in Q# perform operations on the bits of integer values,
// producing a new integer value. The bitwise operators in Q# are
// `~~~`, `&&&`, `|||`, `^^^`, `>>>`, and `<<<`.

function Main() : Unit {

    // `~~~` performs a bitwise NOT on the bits of an integer.

    // The integer value -6.
    let integer = ~~~5;
    Message($"Bitwise NOT: {integer}");

    // The integer value 4.
    let integer = ~~~-5;
    Message($"Bitwise NOT: {integer}");

    // `&&&` performs a bitwise AND on the bits of two integers.

    // The integer value 4.
    let integer = 5 &&& 6;
    Message($"Bitwise AND: {integer}");

    // The integer value 2.
    let integer = -5 &&& 6;
    Message($"Bitwise AND: {integer}");

    // `|||` performs a bitwise OR on the bits of two integers.

    // The integer value 7.
    let integer = 5 ||| 6;
    Message($"Bitwise OR: {integer}");

    // The integer value -1.
    let integer = -5 ||| 6;
    Message($"Bitwise OR: {integer}");

    // `^^^` performs a bitwise XOR on the bits of two integers.

    // The integer value 3.
    let integer = 5 ^^^ 6;
    Message($"Bitwise XOR: {integer}");

    // The integer value -3.
    let integer = -5 ^^^ 6;
    Message($"Bitwise XOR: {integer}");

    // `>>>` performs a signed right bit-shift of a magnitude specified by the
    // right-hand integer on the bits of the left-hand integer.
    // If the right-hand integer is negative, it reverses the direction of the bit-shift.

    // The integer value 1.
    let integer = 5 >>> 2;
    Message($"Right Bit-shift: {integer}");

    // The integer value -2.
    let integer = -5 >>> 2;
    Message($"Right Bit-shift: {integer}");

    // The integer value 20.
    let integer = 5 >>> -2;
    Message($"Right Bit-shift: {integer}");

    // `<<<` performs a signed left bit-shift of a magnitude specified by the
    // right-hand integer on the bits of the left-hand integer.
    // If the right-hand integer is negative, it reverses the direction of the bit-shift.

    // The integer value 20.
    let integer = 5 <<< 2;
    Message($"Left Bit-shift: {integer}");

    // The integer value -20.
    let integer = -5 <<< 2;
    Message($"Left Bit-shift: {integer}");

    // The integer value 1.
    let integer = 5 <<< -2;
