    Pop two words from stack; push Boolean OR IRETURN N/A Return from method with integer value ISTORE variable name Pop word from stack and store in local variable ISUB N/A Pop two words from stack; subtract the top word from the second to top word, push the difference; LDC_W constant name Push constant from constant pool onto stack NOP N/A

  3. Stack (abstract data type) - Wikipedia

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

    The first element, usually at the zero offset, is the bottom, resulting in array[0] being the first element pushed onto the stack and the last element popped off. The program must keep track of the size (length) of the stack, using a variable top that records the number of items pushed so far, therefore pointing to the place in the array where ...

  4. Binary heap - Wikipedia

    en.wikipedia.org/wiki/Binary_heap

    A heap on n elements can be merged with a heap on k elements using O(log n log k) key comparisons, or, in case of a pointer-based implementation, in O(log n log k) time. [14] An algorithm for splitting a heap on n elements into two heaps on k and n-k elements, respectively, based on a new view of heaps as an ordered collections of subheaps was ...

  5. Pushdown automaton - Wikipedia

    en.wikipedia.org/wiki/Pushdown_automaton

    The manipulation can be to push a particular symbol to the top of the stack, or to pop off the top of the stack. The automaton can alternatively ignore the stack, and leave it as it is. Put together: Given an input symbol, current state, and stack symbol, the automaton can follow a transition to another state, and optionally manipulate (push or ...

  7. Binary Golay code - Wikipedia

    en.wikipedia.org/wiki/Binary_Golay_code

    Lexicographic code: Order the vectors in V lexicographically (i.e., interpret them as unsigned 24-bit binary integers and take the usual ordering). Starting with w 0 = 0, define w 1, w 2, ..., w 12 by the rule that w n is the smallest integer which differs from all linear combinations of previous elements in at least eight coordinates.

  8. Tuple - Wikipedia

    en.wikipedia.org/wiki/Tuple

    A 1-tuple and a 2-tuple are commonly called a singleton and an ordered pair, respectively. The term "infinite tuple" is occasionally used for "infinite sequences". Tuples are usually written by listing the elements within parentheses "( )" and separated by commas; for example, (2, 7, 4, 1, 7) denotes a 5-tuple. Other types of brackets are ...

  9. Deterministic pushdown automaton - Wikipedia

    en.wikipedia.org/wiki/Deterministic_pushdown...

    In automata theory, a deterministic pushdown automaton (DPDA or DPA) is a variation of the pushdown automaton.The class of deterministic pushdown automata accepts the deterministic context-free languages, a proper subset of context-free languages.
