We recommend: Shuffle an Array and Min Stack. Tree is slightly more complex than linked list, because the latter is a linear data structure while the former is not. Explore Problems Contest Discuss Interview. In this chapter, we are going to focus on the two-dimensional array to explain: How does a multidimensional array work? In this card, we will introduce array and string. 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. After finishing the previous chapter, we are now familiar with the concept of array and string and are able to perform basic operations in an array or a string. How to perform basic operations initialization, data access, modification, iteration, sort, etc in an array? We have one problem here which is great for practicing breadth-first traversal. Array is one of the fundamental blocks in data structure. For the best practice result, we strongly advise you to go through this list at least a second time, or even better - a third time.

In the previous chapter, we have learned about the one-dimensional array. We also provide a tutorial for you to use the built-in array and dynamic array. As we mentioned in the overview, a string is an array of characters. By using these operations, we are able to solve some basic problems. By the second attempt, you may discover some new tricks or new methods. Do not forget the Two-pointer technique, which not only applicable to Array problems but also Linked List problems as well. In this chapter, we provide a list of more array-related data structures or techniques you might want to know in the future. Here are some other questions that do not fit in other categories.
