Lower Bound on Comparison-based Sorting
Different sorting algorithms may have different time complexity, how to know whether
the running time of an algorithm is best possible?
We know of several sorti
9.3 Linear-Time Selection
We aim to find the i-th smallest element from a set A containing n elements,
1 i n.
The general strategy is to find a pivot element x in A such that a constant fractional

11. Hash Tables
Many applications require a dynamic set that supports only the directory
operations INSERT, SEARCH and DELETE.
A hash table is a generalization of the simpler notion of an ordinary arr
Recurrences
When an algorithm contains a recursive call to itself, its running time can often be
described by a recurrence. A recurrence is an equation or inequality that describes a
function in terms
Asymptotic notations
O(g(n)= cfw_ f (n) : there exist positive constants c and n0 such that
0 f (n) c g(n) for all n n0, e.g. 8 log n = O(n).
(g(n)= cfw_ f (n) : there exist positive constants c and n
Divide-and-Conquer (D&C) Paradigm
Given a problem A , if the D&C strategy is applicable, the problem is then solved
using the strategy. The detailed steps are as follows.
1. Divide A into a number of
6. Heapsort and Priority Queues
Heapsort is an in place sorting algorithm that runs in O(n log n).
It achieves asymptotically optimal running time
It only takes a constant amount of space outside th
Asymptotic notation
In the analysis of algorithms, it is common to estimate the running time in the
asymptotic sense, that is, to estimate the running time for arbitrarily large inputs.
