When preparing for coding interviews, it is important to have a strong understanding of data structures. Here are three popular data structure courses that can help you in your preparation:

1. “Algorithms and Data Structures” by Tim Roughgarden (Coursera):

– This course covers fundamental data structures such as arrays, linked lists, stacks, queues, trees, and graphs, along with algorithms for searching, sorting, and graph traversal. It emphasizes problem-solving techniques and efficient algorithm design. Tim Roughgarden is a renowned professor and his teaching style is highly regarded.

1. “Data Structures and Algorithms” by Abdul Bari (YouTube):

– Abdul Bari’s YouTube channel offers a comprehensive series on data structures and algorithms. The course covers topics such as arrays, linked lists, stacks, queues, trees, heaps, hash tables, sorting algorithms, and graph algorithms. The explanations are detailed and the examples are well-explained, making it a popular resource among coding interview aspirants.

1. “Introduction to Algorithms” by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein (Book):

– Although not a course per se, this book is widely regarded as a go-to resource for learning algorithms and data structures. It provides a comprehensive introduction to various data structures and algorithms, along with detailed explanations and pseudocode. It covers topics such as sorting, searching, dynamic programming, graph algorithms, and more.

These courses are popular among coding interview candidates due to their comprehensive coverage of data structures, algorithms, and problem-solving techniques. Remember that practice and hands-on implementation of these concepts are equally important for success in coding interviews
