Des algorithm is a symmetric cryptosystem in the cryptography system, also known as the United States data Encryption Standard, is the 1972 U.S. IBM developed symmetric cryptography algorithm. The plaintext is grouped by 64 bits, the key is 64 bits long, the key is in fact 56-bit participating DES operations (8th, 16, 24, 32, 40, 48, 56, 64 bits are check bits, So that each key has an odd number of 1) After grouping the plaintext group and the 56-bit key to the bitwise substitution or Exchange m

Image Repair Program-can be used for watermark removalIn real life, we may encounter some beautiful or precious pictures are disturbed by noise, such as the folds of old photos, such as dust or stains on the lens, or some of the things we want to use for me but have a nasty watermark, then there is no way to eliminate these noise?The answer is yes, it is still a good framework that we have used countless ti

, and do not touch which product class should be instantiated this detail.4. Original model mode: By giving a prototype object to indicate the type of object to be created, and then creating more objects of the same type with the method of copying the prototype object. The original model mode allows the product class to be dynamically increased or decreased, and the product class does not need to have any predetermined hierarchy structure, and the original model pattern applies to any hierarchy

Design and implement a data structure for Least recently Used (LRU) cache. It should support the following operations: get and set .get(key)-Get The value ('ll always be positive) of the key if the key exists in the cache, otherwise return-1.set(key, value)-Set or insert the value if the key is not already present. When the cache is reached its capacity, it should invalidate the least recently used item bef
