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

In this lesson, we will solve the following problem:

You are given some integer as input, (i.e. ... -3, -2, -1, 0, 1, 2, 3 ...) and you have to convert the integer you are given to a string. 
Examples:
```
    Input: 123
    Output: "123"
    Input: -123
    Output: "-123"
```


Note that you cannot make use of the built-in `str` function:


In this lesson, you will learn how to convert an integer to a string in Python.
