Leetcode

Coding is an essential skill for research and I found this article very useful. From today on, I am going to ace leetcode problems in Google（71） and Microsoft（58）, and then write a blog to record my process. At the same time, I am going to post top100 liked problems at leetcode in my blog. I have solved them before but forgot many of them. As a result, there will about 200 coding problems.

I am going to divide these problems into the following 15 categories and assign at least one label to the posted coding problem.

1. Sliding Window
2. Two Pointers or Iterators
3. Fast and Slow pointers
4. Merge Intervals
5. Cyclic sort
6. In-place reversal of linked list
7. Tree BFS
8. Tree DFS
9. Two heaps
10. Subsets
11. Modified binary search
12. Top K elements
13. K-way Merge
14. Topological sort
15. Dynamic Programming
