Source, git Heap is a data structure that can fundamentally change the performance of fairly common algorithms in Computer Science. The heap data structure is called a heap because it satisfies the heap property. The heap property states, that if P i…

In a tree, nodes have a single parent node and may have many children nodes. They never have more than one parent nor point to any siblings. The most common tree structure you see is a web page. The underlying structure is often called the "DOM tree&…

A graph is a data structure comprised of a set of nodes, also known as vertices, and a set of edges. Each node in a graph may point to any other node in the graph. This is very useful for things like describing networks, creating related nonhierarchi…
