[10 of algorithm series] Big Data processing tools: bloom filter and bloom Filter[Introduction] in daily life, when designing computer software, we often need to determine whether an element is in a collection. For example, in word processing software, you need to check whether an English word is correctly spelled (that is, whether it is in a known dictionary). In the FBI, whether the name of a suspect is already on the suspect list; whether a website

Who knows that a "View" cannot be "STOPPED ". Actually, it takes up the whole weekend that I was going to use to make up my senses.
Strictly speaking, "amazing" is not a technical book, and the story books may be more appropriate. It is also the feature of this story book that allows your reader to ea
