Why time complexity is better than actual running time?
Finding a time complexity for an algorithm is better than measuring the actual running time for a few reasons:
# Time complexity is unaffected by outside factors; running time is determined as much by other running processes as by algorithm efficiency. # Time complexity describes how an algorithm will scale; running time can only describe how one particular set of inputs will cause the algorithm to perform.
Note that there are downsides to time complexity measurements:
# Users/clients do not care about how efficient your algorithm is, only how fast it seems to run. # Time complexity is ambiguous; two different O(n2) sort algorithms can have vastly different run times for the same data. # Time complexity ignores any constant-time parts of an algorithm. A O(n) algorithm could, in theory, have a constant ten second section, which isn't normally shown in big-o notation.
What is a regression analysis?
Regression analysis is a statistical technique to measure the degree of linear agreement in variations between two or more variables.
[(Multi=many)--( media-way to communicate information)] Multimedia is combination of Text, Audio, Vedio, Images and Graphics.
You would use neither Java nor C++, you would use Objective-C, in conjunction with the Apple iPod API (iPod Library Access).
One less than the product of a number represented by 'X" multiplied by itself twice. That's only one side of an equation, so you can't solve for 'X'.
C program to multiply two complex no?
/*C++ program to multiply two complex numbers using * operator overloading*/
#include<iostream.h>
#include<conio.h>
class complex
{
float x,y;
public:
complex() {}
complex(float real,float img)
{
x=real; y=img;
}
complex operator*(complex);
void display()
{
cout<<x<<" + "<<y<<"i"<<endl;
}
};
complex complex::operator*(complex e)
{
complex temp;
temp.x=x*e.x+y*e.y*(-1);
temp.y=x*e.y+y*e.x;
return(temp);
}
void main()
{
clrscr();
complex c1(5,3),c2(3,2),c3=c1*c2;
c1.display();
c2.display();
cout<<"Multiplication"<<endl;

}
OUTPUT:

9 + 19i
How do you delete an ith element in singly linked list?
You will need to traverse the list i times to get to the element you want deleted. Each time you go thru the list you will need to remember the forward pointer from the previous element because when you get to the element you want to delete the previous forward pointer needs to be pointed to the I + 1 element of the list.
Algorithm for finding the factorial using iterative function?
// returns n!
int fact(int n) {
int f_n = 1;
for(int i = n; i > 1; --i) {
f_n *= n;
}
return f_n;
}
How do you test a web server using telnet?
1. Open up a command shell
2. Enter telnet
3. When it says it is connected, enter GET HTTP/1.1
4. The prompt should spit out some HTML code, indicating that the web server is responding and sending web pages (if only an error page).
A what variable has a value that is read only and cannot be changed during the programs execution?
In most languages this is called a constant.
***edit***
Ty for the answer, I just wanted to throw in the page number for ITT-Tech students.

How do you corrupt a Super Mario 64 data?
Well you see mr. anonymouse, when a train is going at 70 mph and the three legged chicken is going at a staggering 3 milligrams and they collide at the intersection of atlantis, then you know that sgt frog episode 26 is going to be really spot on, and don't forget to turn down the harry potter.
The answer is in your question, Protected Mode.
Also you could say that it is running on Ring3, or also Multi-Tasking Mode.
Which is better to learn Linux or Unix?
Linux is far more common these days than traditional Unix. But as any old system administrator will tell you, learn to learn, don't learn the system. There are numerous differences between the different Linux distros, differences between Linux and Unix, and differences between each of the Unices. Learning everything about each system is a daunting task, and probably near impossible. Rather than, say, learning all of the different command line switches for "ls" on each system, just know how to access a man page.
How are the distinctive characteristics of a service operation illustrated by Hotel Monaco?
Two distinctive characteristics of a service operation are a focus on customer service and the need to create an experience for the consumer. Hotel Monaco provides excellent customer service by offering free Wi-Fi for its customers and working to provide the perfect accommodations. The hotel tries to create an experience by offering unique events such as wine tastings and limousine service.
What is the result of True AND False OR True?
True AND False OR True evaluates to True.
IT seems like it does not matter which is evaluated first as:
(True AND False) OR True = False OR True = True
True AND (False OR True) = True AND True = True
But, it does matter as with False AND False OR True:
(False AND False) OR True = False OR True = True
False AND (False OR True) = False AND True = False
and True OR False AND False:
(True OR False) AND False = True AND False = False
True OR (False AND False) = True OR False = True
Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention.
This makes the original question:
True AND False OR True = (True AND False) OR True = False OR True = True
What is the algorithm to find largest node in a binary search tree?
Since a binary search tree is ordered to start with, to find the largest node simply traverse the tree from the root, choosing only the right node (assuming right is greater and left is less) until you reach a node with no right node. You will then be at the largest node.
for (node=root; node!= NULL&&node->right != NULL; node=node->right);
This loop will do this. There is no body because all the work is done in the control expressions.
No it is not , but if you add 4th top at any site => you have quadrangle with one angle equal 180 degrees. Is it correct?
