  2. Stack (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Stack_(abstract_data_type)

    A stack can be easily implemented either through an array or a linked list, as it is merely a special case of a list. [19] In either case, what identifies the data structure as a stack is not the implementation but the interface: the user is only allowed to pop or push items onto the array or linked list, with few other helper operations.

  3. Double-ended queue - Wikipedia

    en.wikipedia.org/wiki/Double-ended_queue

    Javascript's Array prototype & Perl's arrays have native support for both removing (shift and pop) and adding (unshift and push) elements on both ends. Python 2.4 introduced the collections module with support for deque objects. It is implemented using a doubly linked list of fixed-length subarrays.

  4. Queue (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Queue_(abstract_data_type)

    For example, Perl and Ruby allow pushing and popping an array from both ends, so one can use push and shift functions to enqueue and dequeue a list (or, in reverse, one can use unshift and pop), [2] although in some cases these operations are not efficient.

  5. Peek (data type operation) - Wikipedia

    en.wikipedia.org/wiki/Peek_(data_type_operation)

    The name "peek" is similar to the basic "push" and "pop" operations on a stack, but the name for this operation varies depending on data type and language. Peek is generally considered an inessential operation, compared with the more basic operations of adding and removing data, and as such is not included in the basic definition of these data ...

  6. List of CIL instructions - Wikipedia

    en.wikipedia.org/wiki/List_of_CIL_instructions

    pop: Pop value from the stack. Base instruction 0xFE 0x1E readonly. Specify that the subsequent array address operation performs no type check at runtime, and that it returns a controlled-mutability managed pointer. Prefix to instruction 0xFE 0x1D refanytype: Push the type token stored in a typed reference. Object model instruction 0xC2 ...

  7. JavaScript syntax - Wikipedia

    en.wikipedia.org/wiki/JavaScript_syntax

    An Array is a JavaScript object prototyped from the Array constructor specifically designed to store data values indexed by ... (for example, join, slice, and push).

  8. Shunting yard algorithm - Wikipedia

    en.wikipedia.org/wiki/Shunting_yard_algorithm

    */ /* This implementation does not implement composite functions, functions with a variable number of arguments, or unary operators. */ while there are tokens to be read: read a token if the token is: - a number: put it into the output queue - a function: push it onto the operator stack - an operator o 1: while ( there is an operator o 2 at the ...

  9. Data type - Wikipedia

    en.wikipedia.org/wiki/Data_type

    For example, a stack has push/pop operations that follow a Last-In-First-Out rule, and can be concretely implemented using either a list or an array. Abstract data types are used in formal semantics and program verification and, less strictly, in design .
