Practice exercise: Algorithm & Pseudocode Algorithm: A step-by-step problem-solving process that defines how a task is performed. Those steps are: 1) analyze the problem, 2) list the main tasks, 3) write the remaining modules, 4) resequence and revise as necessary. Pseudocode: A language designed to express algorithms. 1. Compose pseudocode to express an algorithm to add three numbers together and when the sum is not negative print it, otherwise print an exception message. 2. List the steps to input three values then output them in reverse order. 3. Repeatedly input and print three integers as long as the first integer input is not negative. 4. Write a pseudocode for a program that is to input a limit(count) for the number of values to input, then input and sum that number of values. Print the sum. 5. Construct a pseudocode algorithm to input the number of pairs of values to be entered; then input and output each pair in ascending order. 6. Show the steps to input and sum positive numbers until 10 have been counted. Ignore zero or negative numbers. Print the sum. 7. List the steps to input three integers then print them in numeric order. 8. Write an algorithm to input a four-digit integer value, then output the individual digits.
