Randomized Select Algorithm

A randomized algorithm is defined as one that uses a certain amount of randomization in its logic or operation. It is said to be an algorithm that depends on the random number to perform its operation. It is used for reducing the overall time complexity, space complexity in the standard algorithm. The randomized algorithm uses the concept of random numbers to find the solutions to the different kinds of problems and also to improve the problem solutions.

Question

### Problem Statement

Given the array `A = [3, 7, -4, 12; -5, 9, 10, 2; 6, 13, 8, 11; 15, 5, 4, 1]`, what instruction is needed to create the following arrays from A?

### Required Arrays

a. \( B = \begin{bmatrix} -5 & 10 \\ 6 & 8 \end{bmatrix} \)

b. \( C = \begin{bmatrix} 3 & -5 \\ 6 & 15 \end{bmatrix} \)

### Explanation

#### Array A:
Array A is a 4x4 matrix:

\[
A = \begin{bmatrix}
3 & 7 & -4 & 12 \\
-5 & 9 & 10 & 2 \\
6 & 13 & 8 & 11 \\
15 & 5 & 4 & 1
\end{bmatrix}
\]

#### To create Array B:

\[
B = \begin{bmatrix}
-5 & 10 \\
6 & 8
\end{bmatrix}
\]

**Instruction:**
- Extract the submatrix from positions (2,1) to (3,3) in A:
- `A(2:3, 1:2)`

#### To create Array C:

\[
C = \begin{bmatrix}
3 & -5 \\
6 & 15
\end{bmatrix}
\]

**Instruction:**
- Extract elements from positions (1,1), (2,1), (3,1), and (4,1) of A:
- `A([1 2 3 4], 1)` (reshape to 2x2 matrix if necessary)

Language: C Write a program that will allocate memory to an array of the size specified by the user at runtime. Use malloc and free. Fill the array, print the elements and calculate the average value. A. In the main function: a) Ask the user for the size of the array. b) Using the malloc function allocate the double array of the size specified by the user. c) Check if the allocation was successful. - If the address returned by malloc is not NULL, use the rand function in a for loop and assign pseudorandom values to the array elements. Then call the function averagevalue. Print the result. Free up memory with the free function. - If the allocation failed and the address returned by malloc is NULL, print the message and exit the program. B. Define the function averagevalue and then call it in main. The function calculates the average value of the elements of the array passed as an argument and prints the array elements to the screen. The function returns the average value. C. Use…
