The set collection has no index value and cannot be repeated. The bottom layer is map. When adding an element, the hashCode() method will be called first to calculate the hash value of the object, and then use the hash value % of the array length to calculate the index value position of the new […]

HashSet deduplication principle
1. What is Hashset Collections in Java are divided into Collection collections (single-column collections) and Map collections (double-column collections) The Hashset collection is an implementation class of the set interface. The set interface also inherits from the top-level parent class Collection interface, so HashSet can have methods common to Collection. The characteristics of the set […]

21.11 Python uses CRC image deduplication
Using CRC32 can also realize the image deduplication function. The following FindRepeatFile function performs crc verification on all files after running and adds the check value. Store it in the CatalogueDict dictionary, then extract the CRC feature values and store them in the CatalogueList list, and then count the number of occurrences of the feature […]
Linux dup and dup2
Linux dup and dup2 functions, what are the differences between them, what scenarios will they be used in, and what precautions should be taken when using them dup and dup2 are both system calls in Linux systems, used to copy file descriptors. Their main difference is how new file descriptors are specified and how new […]
