Bitwise Operations

A decimal number can be represented as a sequence of bits.

To illustrate:

6 = 00000110
23 = 00010111

From the bitwise representation of numbers, we can calculate the bitwise AND, bitwise OR and bitwise XOR.

Using the example above:

bitwiseAND(6, 23) ➞ 00000110
bitwiseOR(6, 23) ➞ 00010111
bitwiseXOR(6, 23) ➞ 00010001

Write three functions to calculate the bitwise AND, bitwise OR and bitwise XOR of two numbers.

Examples:

bitwiseAND(7, 12) ➞ 4
bitwiseOR(7, 12) ➞ 15
bitwiseXOR(7, 12) ➞ 11

Notes:

JavaScript has a useful function: toString(2), where you can see the binary representation of a decimal number.
