Discover data structures and algorithms using Python. Gain insights into solving real-world problems and typical interview questions with detailed reviews, explanations, and hands-on coding exercises.

Data structures and algorithms are among the most fundamental concepts of Computer Science. Whether it’s real-world problems you’re trying to solve or the typical coding question asked in an interview, almost every problem requires you to demonstrate a deep understanding of data structures and algorithms. 

This course is a detailed review of some of the most common data structures and algorithms that you’ll see in interviews and your everyday work. With implementation details, thorough explanations, and hands-on coding exercises, you’ll quickly gain the confidence you need to solve any problem, no matter the situation.

Data Structures and Algorithms in Python

# Problem

In this exercise, you are given some numeric string as input. You have to convert the string you are given to an integer. 

**Do not make use of the built-in `int` function.**

Example:
```
    "123" -> 123
    "-12332" -> -12332
    "554" -> 554
```

Challenge yourself with an exercise in which you'll have to covert a string into an integer.
