Specifications for stack

We normally use the decimal (denary). system, also called base 10. l There are 10 different symbols .(digits). l 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 l To count higher than nine we re-use the symbols by putting them in columns. l The value of aComputers use the binary system, also called base 2 l There are two different symbols (digits) l 0, 1 l To count higher than one we re-use the symbols by putting them in columns l The value of a symbol depends on its position symbol depends on its position....

The nonreducing end of the substrate-binding site of human salivarya-amylase contains two residues Trp58 and Trp59, which belong tob2–a2 loop of the catalytic (b/a)8 barrel. While Trp59 stacks onto the substrate, the exact role of Trp58 is unknown. To investigate its role in enzyme activity the residue Trp58 was mutated to Ala, Leu or Tyr. Kinetic analysis of the wild-type and mutant enzymes was carried out with starch and oligosaccharides as substrates. All three mutants exhibited a reduction in specific activity (150–180-fold lower than the wild type) with starch as substrate....

A Graph G consists of a set V, whose members are called the vertices of G, together with a set E of pairs of distinct vertices from V. • The pairs in E are called the edges of G. • If the pairs are unordered, G is called an undirected graph or a graph. Otherwise, G is called a directed graph or a digraph. • Two vertices in an undirected graph are called adjacent if there is an edge from the first to the second.

AVL Tree is: • A Binary Search Tree, • in which the heights of the left and right subtrees of the root differ by at most 1, and • the left and right subtrees are again AVL trees. The name comes from the discoverers of this method, G.M.Adel'son-Vel'skii and E.M.Landis. The method dates from 1962. .Balance factor Balance factor: • left_higher: HL = HR + 1 • equal_height: • right_higher:

Contiguous Stack Applications of Stack .Linear List Concepts LIFO (Stack) .Stack ADT DEFINITION: A Stack of elements of type T is a finite sequence of elements of T, in which all insertions and deletions are restricted to one end, called the top. Stack is a Last In - First Out (LIFO) data structure. Basic operations: • Construct a stack, leaving it empty. • Push an element. • Pop an element. • Top an element.

Figure 2.1 shows how the post-byte is calculated for a Push or a Pull. Specifically the System stack is shown; if the User stack is being employed then U is replaced by S. Figure 2.3 shows a snapshot of memory after a Push onto the System stack.
