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

In this lesson, given a string, we develop an algorithm to return the first occurring uppercase letter. We will solve this problem using an iterative and recursive approach:

For instance, for the strings:
```
str_1 = "lucidProgramming"
str_2 = "LucidProgramming"
str_3 = "lucidprogramming"
```
The algorithm should return `P`  `L`, and output a message indicating that no capital letter was found for `str_1`, `str_2`, and `str_3`, respectively.

## Iterative Approach

Let's have a look at the code in Python, which uses the iterative approach:
