On the Suitability of Suffix Arrays for Lempel
... solve the sub-string problem almost as efficiently as an ST [3]; moreover, its use is more appropriate when the alphabet is large. An SA can be built using a sorting algorithm, such as “quicksort”; it is possible to convert an ST into an SA in linear time [3]. An SA does not has the limitation of an ...

... need to perform. We first examine the number of pointers we have to backtrack to climb from level 1 (of the element immediately before the element searched for) up to level L(n). We assume we have no knowledge of the levels of elements in the list, and that we always reach level L(n) before we reach ...

Ans: During recursion, a global variable could be used to control the depth of recursion, or data pushed onto some stack could provide a termination condition; and in the latter case this termination condition is usually related to the form ...

B-tree
In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree is a generalization of a binary search tree in that a node can have more than two children (Comer 1979, p. 123). Unlike self-balancing binary search trees, the B-tree is optimized for systems that read and write large blocks of data. B-trees are a good example of a data structure for external memory. It is commonly used in databases and filesystems.
