Given the following algorithm fragment in pseudocode: SET x TO 5 SET y TO x + 2 SET x TO y + 3 What is the value of x at the end of the execution?

Consider the following pseudocode for an algorithm: SET total TO 0 FOR i FROM 1 TO 5 DO SET total TO total + i END FOR What will be the value of total after the loop has finished execution? Show your working / calculation for each iteration.

A simple algorithm in pseudocode is given below: FUNCTION CalculateTotal(numbers) SET sum TO 0 FOR EACH number FROM numbers DO SET sum TO sum + number END FOR RETURN sum END FUNCTION A student executed the algorithm using the list [3, 7, 2, 5]. Determine the final value returned by the CalculateTotal function. Show your

An algorithm uses a counter count and a total accumulator total. The algorithm adds up numbers from 1 to a given limit. The pseudocode is as follows: SET count TO 1 SET total TO 0 WHILE count

An algorithm calculates the factorial of a number provided by the user. The factorial of a number n, represented as n!, is the product of all positive integers up to n. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120.
