Writing a recursive algorithm

The question of how many ways a committee of 4 people can be selected from a group of 10 is known as a combination. The notation in general for counting the number of ways of selecting r items from a group of n is C(n,r) = n! / r!(n-r)! Also, given that 0! = 1 by definition, we can show that C(n,0) = 1 = C(n,n) Also, C(n,r

Programming: Gantt Chart

Assume you have a project with seven activities Labeled A-G, as shown below.

Write a C program that displays the content of array passed as an argument.

Write a C program that has a declaration in main function to store the following numbers into an array named channels: 2, 4, 5, 7, 9, 11, 13. There should be a function call to display function that accepts the channels as an argument named channels and then displays the numbers using the pointer notation *(channels + i). Mod

CBC mode

4)The cipher block chaining (CBC) mode has the property that it recovers from errors in cipher text blocks. Show that if an error occurs in the transmission of a block , but all the other blocks are transmitted correctly, then this affects only two blocks for decryption, which two blocks?

Write a C program that accepts as input from the keyboard a floating point number, an integer, and a character. Each of these inputs should be preceded by a prompt and stored using individual variable names. Have your program call a function that assembles the input data into a single string. Display the assembled string using t

Determining Minimum and Shortest Paths: Example Problem

Use the accompanying graph to determine minimum and shortest paths. For minimum path, give the total weight. For the shortest path, give the total path length. In each case, list a path providing the minimum value. See attached graph. (a). Shortest-path distance from C to D (b). Shortest-path distance from E to B (c).

Graphical Characteristics

Please see attached file. (a). List the vertices in graph A in the reverse order of their visit (finish) time for a depth-first search that starts at vertex A. Repeat the process, and produce a different list by assuming that the scan accesses neighbors in a different order. (b). List the vertices in graph B in the reverse
