Course Overview

Some of the toughest questions in technical interviews require dynamic programming solutions. Dynamic programming (DP) is an advanced optimization technique applied to recursive solutions. However, DP is not a one-size-fits-all technique, and it requires practice to develop the ability to identify the underlying DP patterns. With a strategic approach, coding interview prep for DP problems shouldn’t take more than a few weeks. This course starts with an introduction to DP and thoroughly discusses five DP pa...Show More

Frequently Asked Questions

What is the difference between memoization and tabulation in dynamic programming?

Memoization is a top-down approach in which recursive calls are made, and solutions to subproblems are stored in memory to prevent redundant calculations. Tabulation, in contrast, is a bottom-up approach in which you iteratively solve subproblems and fill out a table from the base case to the final solution. Both techniques help improve efficiency but are used based on the problem’s nature.

How can I practice dynamic programming to improve interviews?

You can practice dynamic programming problems on LeetCode and Educative. Begin with well-known DP problems such as Fibonacci, 0/1 Knapsack, and Longest Common Subsequence. Solving these basic problems will help you build a foundation before tackling more advanced problems frequently appearing in interviews.

How can I recognize if a problem is suited for dynamic programming?

It likely requires dynamic programming if a problem involves repeated subproblems or recursive calls where solutions are recomputed. Problems asking for “optimal” results, such as maximum profit, shortest path, or longest sequence, indicate that DP may be needed to avoid redundant work and improve efficiency.

Why is dynamic programming emphasized in technical interviews?

Interviewers focus on dynamic programming because it tests your ability to break complex problems into smaller, manageable parts. DP questions challenge candidates to think critically, optimize for efficiency, and use resources effectively—skills highly valued in software engineering roles.
