Remember: Deliberate practice does not mean looking for answers and memorizing it. After this chapter, you will: Be familiar with the basic operations in a string, especially the unique operations which we don't have in an array Understand the differences between different comparison functions; Determine whether the string is immutable or not in your favorite language and understand the impact of this feature; Be able to solve basic string-related problems. We will keep publishing more cards and update the links in this article to help you conquer these topics one by one. How to perform basic operations initialization, data access, modification, iteration, sort, etc in an array? We recommend: Number of 1 Bits and Valid Parentheses. Array is one of the fundamental blocks in data structure. Another technique to greatly simplify coding in linked list problems is the dummy node trick. We have one problem here which is great for practicing breadth-first traversal. The more you are able to solve a problem yourself without any reference to answers, the more you will improve. We recommend: Shuffle an Array and Min Stack. Back to Explore. Linked List problems are relatively easy to master. Here are some other questions that do not fit in other categories.

Back to Explore. These are the basic data structure you should be familiar with. How to use a two-dimensional array to solve problems? Register or Sign in. By using these operations, we are able to solve some basic problems. Remember: Deliberate practice does not mean looking for answers and memorizing it. However, it is obviously not enough. Since a string is just formed by an array of characters, they are both similar. These problems may require you to implement a given interface of a class, and may involve using one or more data structures. Array type of questions were asked in interviews frequently. In this chapter, we are going to focus on the two-dimensional array to explain: How does a multidimensional array work? Another technique to greatly simplify coding in linked list problems is the dummy node trick. By the second attempt, you may discover some new tricks or new methods. In this card, we will introduce array and string. Here are some classic Dynamic Programming interview questions.
