Bloom Filter was proposed by Bloom in 1970. It is actually a very long binary vector and a series of random ing functions.
The bloom filter can be used to retrieve whether an element is in a collection.
Its advantage is that the space efficiency and query time far exceed the average algorithm. Its disadvantage is that it has a certain false recognition rate and difficulty in deletion.[Working principle]
