stored in the positions mapped by two hash functions, instead of the number of existing keys in two subtables.
After learning about 2-left hashing and D-left hashing, it is easy to understand. It is just an extension of the former. 2-left hashing: the number of sub-tables is 2, and D-left hashing is more flexible. The number of sub-tables is a variable D, which also means that the number of hash functions is D. In D-left hashing, the entire hash table is divided into D sub-tables adjacent fr
(chain): A path of non-elongation, which is connected by the end of several solid edges, is called the real path. By the definition of real edges, the point depth on the real path is different and is a continuous natural number. Among them, the non-elongation means that the lightest node on a real path is u, then the edges between the parent nodes of U and u cannot be real edges, and the deepest node of a real path is V, and the edges connected by V

While learning new technologies, we should always review the data structures and classicAlgorithm.
1. The simplest sorting method is the Bubble sorting method. The basic idea of this method is to regard the elements to be sorted as vertical "Bubbles", and the smaller elements are relatively light, so as to move up and down. In the Bubble sorting algorithm, we need to process the "bubble" sequence several times. The so-called one-time processing is to check the sequence from the bottom up, and

Classic sorting Algorithm (Java edition) reprint1. Bubble Sort BubbleThe simplest sort method is the bubble sort method. The basic idea of this approach is to think of the elements to be sorted as "bubbles" that are vertically arranged, smaller elements lighter and thus upward. In the bubble sorting algorithm we have to deal with this "bubble" sequence several times. The so-called process, is to check the sequence from the bottom up, and always pay attention to the sequence of two adjacent eleme
are below, exchanging their positions. Obviously, after processing, the "lightest" element floats to its highest position, and after two times, the "light" element floats to the next high position. In the second pass, you do not have to check because the element at the highest position is already the lightest element. In general, when I pass the processing, I do not have to check the higher position above
