... operation involves being given a string X, and looking for all the strings in S that contain X as a prefix. 12.3.1 Standard Tries Let S be a set of s strings from alphabet σ such that no string in ... subsequence of both X and Y. Since X and Y are character strings, we have a natural set of indices with which to define subproblems—indices into the strings X and Y. Let us def...

... for inserting an element at the beginning of a singly linked list. Assume that the list does not have a sentinel header node, and instead uses a variable head to reference the first node in ... space in memory). Example 3.2: Much of the syntax in modern programming languages is defined in a recursive way. For example, we can define an argument list in Java using the followin...

... finding such a tree are the focus of this section. Problem Definition Given a weighted undirected graph G, we are interested in finding a tree T that contains all the vertices in G and minimizes ... Rather than computing a shortest path tree from some particular vertex v, we are interested instead in finding a (free) tree T that contains all the vertices of G and has the minimu...

For instance, we could define a ... by their indices is called an array list (or vector, using an older term). Since our index definition is more consistent with the way arrays are indexed in Java and other programming l...

... nonlinear data structures in computing—trees. Tree structures are indeed a breakthrough in data organization, for they allow us to implement a host of algorithms much faster than when using linear ... binary tree. This interfaces extends Position, thus inheriting method element, and has additional methods for setting the element stored at the node (setElement) and for se...
