 Before moving on to particular problems, we must clarify that we can solve them more efficiently with **additional knowledge in programming with Java** (methods, arrays, collections, recursion, etc.). Each solution that we will provide now only uses the material covered in this book. The goal is to learn how to construct **more complex algorithms** based on your knowledge up to the present moment.

 The input of our problem consists of a few components:
 - On the **first line, we have all the money** that Lina has for shopping.

 The first part of the reading is trivial. We should keep in mind that we will be using the **`BigDecimal`** type because we are working with money, and we need precise accuracy:

 Let's examine the first two sub-problems for our algorithm. The first sub-problem concerns the way we read the commands until we reach the **"mall.Exit"** command. The solution that we previously saw uses a **`while-loop`**. The second sub-problem is to **access each symbol** of the command passed. Keeping in mind that the input data with the commands is a **`String`** type, the easiest way to access each symbol inside the strings is via a **`foreach` loop**.

 Bonny is an extremely powerful witch. Because her natural power is not sufficient to successfully fight vampires and werewolves, she has started to master the power of Expressions. An expression is hard to master because the spell relies on the ability to **quickly solve mathematical expressions**.
