A user should have the choice of 1. which sorting algorithm to use to sort the numbers (selection, bubble, insertion, quick) 2. how many numbers are to be sorted in the list 3. whether the list is sorted in ascending or descending

Write a C# GUI application named IS318_W3A1_ that meets the following requirements: a. Program must use at least three different types of controls b. Program must demonstrate the use of event handling for implementation of program logic c. Program must demonstrate data transfer between user controls and data structures using data binding or direct

The formula for a combination of n objects in groups of r is n(nr). A use for this formula would be to calculate how many ways five people can win a race where there is a 1st, 2nd and 3rd place. This is the same as saying how many ways can you order five objects in only three positions. Using the above formula we would set n5 and r3 and

For n 1, in how many out of the n permutations ((1), (2).....(n)) of the numbers (1,2,...,n the value of x(i) is either i1, or i, or i 1 for all 1 i n Example The permutation (21354) follows the rules while the permutation (21534) does not because (3) 5. Hint Find the answer for small n by checking all the permutations and then find the

Write a C++ program to insert or delete characters in a buffer. You need to develop an abstract data type for a buffer in the text editor program that implements the following operations using linked list : Create an empty buffer createBuffer() Insert a character at the cursor position insert(char c) Get the character
