Stack is a linear data structure which follows a particular order in which the operations are performed. The order may be LIFO(Last In First Out) or FILO(First In Last Out). The Ds\Stack uses Ds\Vector internally.
Requirements: PHP 7 is required for both extension and the compatibility polyfill.
Installation: The easiest way to install data structure by using the PECL extension.
