Bitwise operations basic exercise

[tekkac]

Description

Bitwise operations such as AND, OR, and XOR, are not basic operations for felts. The Bitwise builtin is an ad-hoc module to enable those common operations and require implicit arguments.

Write a basic exercise to demonstrate how to use bit-wise in Cairo.

Resource:

• https://www.cairo-lang.org/docs/reference/common_library.html#common-library-bitwise

Acceptance criteria

• Add a common library exercise on bit-wise operation using builtins
• The contract compiles and tests pass
• An exercise patch is generated
