I write this book to help myself summarize data structure and algorithm frequently used in coding interview. Leetcode is a online judge platform which has 608 algorithms for you to practice by 30 June 2017

I'm using C# as primary language to present code snippet. Although, there are some Cons. There are some common data structures which are critical to solve some problems. e.g. Priority Queue, Sorted List (Support duplicate). There are few people in leetcode using C# to solve the problems. Usually, you get less support from leetcode discussion. Most popular language in leetcode is C++, Java, Python. With some C++, Python's language feature, people could write really short and elegant solution than any other language. I may consider learn Python and add Python support for this book later.
