Problem set has covered all the important approaches for cracking any coding interview . You could easily apply these ideas to solve other similar problems.
Several problems in the set can be solved using more than one approaches . This will help you to understand ideas to improve the time and space complexity.
We recommend to follow these five steps of problem solving :
- Understanding the problem
- Designing the brute force or basic solution
- Improving the time and space complexity
- Writing pseudo code on paper and checking boundary conditions
- Programming language implementation and running the test cases
If you have any difficulty in solving problems in a topic then we encourage to learn or revise key concepts related to the topic. Key idea of learning algorithm is - Doing practice and never give up!
