Prologue

This book records my second practice on Leetcode Online Judge. It provides the thinking and solution for some typical questions in Leetcode. It is used for my technology Interview and strengthen my skills on algorithms and data structures.

This Git book will be illustrated in the order of how familiar I am with the related parts. And it will also contain some contents from the GeekforGeeks.org of the related background algorithm knowledge.

This part serves as a reminder to me as the purpose and significance of this book. Wish I remember this and insist till the day I get my expected job.
