I. Data Types(Data type): Perl has four data types: Scalar (variable), Scalar Array (Array), Hash Array (Hash), and References (pointer ), it seems to be rare, but it is more than enough to use it. Especially when writing Perl programs, you do not

Some of the most critical aspects of a hash table are: Access via key (calculates key by hash function) Mapped to data structures (the storage structure of the hash table itself) Processing of mappings (conflict or collision

What is Perl? Perl is a free and open-source scripting language created by Larry Wall. This language is mainly intended for practical and rapid development, Structured Programming is incompatible with the popular object-oriented programming.

Map in go is used to store key/value pairs. It is often called hash, dictionary, and associated array in other places. These are different names for the same data structure, they are all used to map keys to values after hash function processing to

The hash algorithm of PHP core technology and best practice The hash table is also called a hash list, which accesses the record by mapping the keyword key to a location in the array to speed up the lookup. This mapping function is called the hash

Four basic data types in Perl (as far as I know): Scalar, array, list, and hash. Scalar should be the atomic Data Structure in Perl, which cannot be further decomposed by programmers, such as int and double in C language. For scalar, I have the
