The complexity Ladder:
In computer science, Exponential growth is the most-danger growth pattern. Algorithms which grow this way are fundamentally useless for anything except for very small input size.
Table 1 compares several algorithms in terms of their complexities.
Table 2 compares the typical running time of algorithms of distinct orders.
The growth patterns above have been tabulated in order of enhancing size. That is,
O(1) < O(log(n)) < O(n log(n)) < O(n2) < O(n3), ... , O(2n).
Notation
Name
Example
O(1)
Constant
Constant growth. Does
not grow as a function
of n. For example, accessing array for one element A[i]
O(log n)
Logarithmic
Binary search
O(n)
Linear
Looping over n
elements, of an array of size n (normally).
O(n log n)
Sometimes called
"linearithmic"
Merge sort
O(n2)
Quadratic
Worst time case for
insertion sort, matrix multiplication
O(nc)
Polynomial,
sometimes
O(cn)
Exponential
O(n!)
Factorial

The two famous methods for traversing are:- a) Depth first traversal b) Breadth first
Algorithm for deletion of any element from the circular queue: Step-1: If queue is empty then say "queue is empty" & quit; else continue Step-2: Delete the "front" element
Program segment for deletion of any element from the queue delete() { int delvalue = 0; if (front == NULL) printf("Queue Empty"); { delvalue = front->value;
The Space - Time Trade Off The best algorithm to solve a given problem is one that needs less space in memory and takes less time to complete its implementation. But in practic

Circular Queues:- A more efficient queue representation is get by regarding the array Q(1:n) as circular. It becomes more convenient to declare the array as Q(O: n-1), when re
Retrieval of information is made simpler when it is stored into some predefined order. Therefore, Sorting is a very important computer application activity. Several sorting algorit
B Tree Unlike a binary-tree, every node of a B-tree may have a variable number of keys and children. The keys are stored in non-decreasing order. Every key has an associated ch
