How to solve any coding problem
Do you want to learn how to crack any coding problem with ease and confidence? Do you want to know how to approach, analyze, and code a solution for any problem that you encounter? Do you want to see how to use examples, flowcharts, and optimization techniques to improve your coding skills? If you answered yes to any of these questions, then this video is for you!
In this video, I will teach you how to solve any coding problem using a simple and effective method1. Coding problems are common in interviews, online platforms, and real-world projects. They test your ability to think logically, creatively, and efficiently. However, many students struggle with coding problems because they don’t have a clear and systematic way of solving them.
That’s why I will show you a 3-step approach that you can use to solve any coding problem1. The 3 steps are:
Step 1: Understand the problem deeply. Read the problem statement carefully and identify the input, output, constraints, and expected time complexity of the problem. Ask any clarifying questions or make any reasonable assumptions. Find any clues or hints that can help you solve the problem.
Step 2: Take your own example. Start with a very small or null input and see what the output should be. Then, increase the size or complexity of the input and observe how the output changes. Draw a flowchart to show the steps involved in your solution. Find the topics or concepts that are relevant to the problem and see if you have solved any similar problems in the past. Find the brute force solution that works for all the cases and produces the correct output. Then, find any repetitions or patterns in your solution and try to optimize it by using any data structures, methods, or tricks that can reduce the time or space complexity of your solution.
Step 3: Dry run and code the solution. Test your solution using some sample inputs and outputs. Write down the values of the variables and the output at each step of your solution. Check if your solution works for all the cases, including the edge cases and corner cases. Write the code for your solution in C++. Follow the coding standards and conventions. Use meaningful variable names and comments. Format your code properly and indent it correctly. Run your code using an online compiler and verify the output.
By the end of this video, you will have a solid understanding of how to solve any coding problem using a 3-step approach. You will also be able to apply this method to any problem you encounter, whether it is on GeeksforGeeks, LeetCode, CodeChef, or any other platform.
