Goes over the six bitwise operators and the common ways they are used.

Example - Addition Example - Multiplication


CPH	10.2 - Bit Operations
CF	Bitwise operations for beginners	Great explanation by Errichto
GFG	Bitwise Operators in C/C++	The same operators are used in java and python

Let's take a look at some examples to better understand bitwise operators. Note that you typically won't be asked to use bitwise operators to implement addition/multiplication.

Example - Addition

Try implementing addition using bitwise operators! You can test your implementation here.

Solution

Example - Multiplication

Now try implementing multiplication using bitwise operators! If you want to test your implementation of multiplication, you can do so here.
