An array of 11 integers is being sorted in ascending order using Quicksort.
Suppose the algorithm has just finished the first pass of partitioning and pivot swapping thus changing the content of the original array into the following array:
[101, 103, 110, 106, 107, 100, 109, 111, 104, 112, 115]

From the resulting array above, determine how many integers could have been the pivot?
Note: elements == pivot are partitioned to the right.

Write a C++ program to achieve the following objectives.
(i) To read elements of two matrices A and B of dimension 3x3.

3. The tractrix is the curve parametrized by ~x(t) = (t − tanh t,sech t).
(a) Find the arc length function s(t) for the above parametrization.
(b) Find a unit speed parametrization of the tractrix.

Can I use domain for my site thats similar to some other company (not exact same but similar)?
For example there is a company domain named "sportsitems.com", now can I use "sportsitemss.com" (with double "s"). Is it legal or not?

Practical 3 (while loop)
Write a program that uses while loops to perform the following steps:
a. Prompt the user to input two integers: firstNum and secondNum
(firstNum must be less than secondNum).
b. Output all odd numbers between firstNum and secondNum.
c. Output the sum of all even numbers between firstNum and secondNum.
d. Output the numbers and their squares between 1 and 10.
e. Output the sum of the square of the odd numbers between firstNum and secondNum.
f. Output all uppercase letters.

Write C++ functions to perform the following tasks.
(i) palindrome(A, size) – this function receives one dimensional character array
‘A ‘ of size ‘ size ‘ as input and returns a character ‘P’
or ‘ N’ respectively, depending on whether the word is a
palindrome or not. If the entered word and the reverse
of it have the same pattern, then the word is a palindrome.

A company distributes 5 different items around Nairobi through its 10 salesmen. Using arrays write a C# application program to input a salesman name and the corresponding sales made by each of the salesman for each of the item. The program should then output each of the salesman’s name, sales, total sales as well as grand total using the format shown below.
Name Item1 Item2 Item3 Item3 Item4 Item5 TotalSales

Write a complete C# application program to calculate the area of a triangle, rectangle or circle. The program should have a decision making statement(s) to decide:
 If the figure is a triangle then ask for base and height values to input.
 If the figure is a rectangle the ask for length and breath values to input
 If the figure is a circle then ask for the radius values to input
The program should display the output on the screen and should enable the user to re-enter choice for at most three times incase a wrong selection is entered

Write C# application program to be used to evaluate the credit worthy of a client. The program reads the credit limit and the price and quantity of the item to be purchased by the client. If the value of the goods is more than the credit limit, the program displays “Sorry you cannot purchase goods worthy such a value on credit” and allows the customer to re-enter the quantity, otherwise, displays “Thank You for purchasing from us” and the value of the purchase. This should be repeated for n customers.
