Computational Systems

The computation systems can be defined as the systems that are capable of solving a problem that includes calculations either mathematical or logical, and are able to produce the result as an output. For example, a simple calculator that is given a set of numbers and operators as input and produces the result as an output can be defined as a computational system. The above example is a simple illustration only, the computational systems range from simple devices to complex devices such as the systems that control the SpaceX companies, Starlink satellites which are being quite recently seen in the skies at many places globally.

Question

Write a function named second-largest in Scheme that takes a list of numbers and uses fold (or reduce) to return the second largest element on the list.

You must use either fold or reduce to do the vast majority of the work. (You may do a little pre- and post- processing outside the call to fold.) You may use the built-in fold method by adding the line (require 'list-lib), or you can use your own implementation.

The built-in fold function has parameters in this order: action partial-result lst.

You may assume that the list contains at least one element.

For example,

(second-largest '(5)) should return 5
(second-largest '(1 3)) should return 1
(second-largest '(8 6 7 5 3 0 9)) should return 8

**How to Implement `second-largest` Function in Scheme**

In this lesson, we’ll learn to write a function called `second-largest` in Scheme. This function will take a list of numbers and return the second largest number from the list. For implementation, we'll primarily utilize the `fold` or `reduce` functions.

### Key Points:

- **Use of `fold` or `reduce`:** You must employ either of these functions for the main logic. Minimal pre- and post-processing outside the call to `fold` is acceptable.
- **Built-in `fold`:** You can leverage Scheme’s built-in `fold` function by adding `(require 'list-lib)` to your code. Alternatively, you can craft your custom `fold` implementation.
- **Parameters of `fold`:** The function accepts parameters in the following order: `action`, `partial-result`, `lst`.

### Assumptions:
- The list will contain at least one element.

### Examples:

1. `(second-largest '(5))`
- **Output:** 5

2. `(second-largest '(1 3))`
- **Output:** 1

3. `(second-largest '(8 6 7 5 3 0 9))`
- **Output:** 8

By following these instructions, you can effectively create a function that correctly identifies the second largest element in any given list.

*C Language The greatest common divisor of integers x and y is the largest integer that divides both x and y. Write a recursive function GCD that returns the greatest common divisor of x and y. The GCD of x and y is defined as follows: If y is equal to zero, then GCD(x, y) is x; otherwise GCD(x, y) is GCD(y, x % y) where % is the remainder operator.
Drawing a right side up triangle Write a recursive function called DrawTriangle() that outputs lines of '*' to form a right side up isosceles triangle. Function DrawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting. Hint: The number of '*' increases by 2 for every line drawn. Ex: If the input of the program is: 3 the function DrawTriangle() outputs: * *** Ex: If the input of the program is: 19 the function DrawTriangle() outputs: * *** ***** ******* ********* *********** ************* *************** ***************** ******************* Note: No space is output before the first '*' on the last line when the base length is 19. in c++

Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.
