Explain the differences between an algorithm and a flowchart with examples.

An algorithm is a sequence of well-defined, step-by-step instructions that provide a solution to a specific problem. It is usually written in a programming language or in pseudocode and is concerned with the logical flow of solving the problem. For example, an algorithm to find the maximum of two numbers would involve comparing the two … Read more

Write an algorithm to print the multiplication table of a number in reverse order.

Print the multiplication table of a number in reverse order Problem Statement: Given a number, print its multiplication table in reverse order. Algorithm: Start Input the number (N). For each multiple from 10 to 1 (i.e., 10, 9, 8, …, 1), do the following: Multiply N by the current multiple. Print the result of the … Read more

Write an algorithm to find the product of the given numbers. PRODUCT = 1 × 3 × 5 × 7 × 9 × 11 × 13 × 15

The product of a given sequence of numbers Problem Statement: Given a sequence of numbers: 1, 3, 5, 7, 9, 11, 13, 15, find their product. Algorithm: Start Initialize a variable product to 1. Multiply each number in the sequence with product: Multiply product by 1. Multiply product by 3. Multiply product by 5. Multiply … Read more

Write an algorithm to find the sum of the given sequence. SUM = 20 + 25 + 30 + 35 + 40 + 45 + 50 + 55 + 60

The sum of a given sequence Problem Statement: Given a sequence: 20, 25, 30, 35, 40, 45, 50, 55, 60, calculate the sum. Algorithm: Start Initialize a variable sum to 0. Add each number in the sequence to sum: Add 20 to sum. Add 25 to sum. Add 30 to sum. Add 35 to sum. … Read more

Write an algorithm that inputs length in inches and calculates and prints it in centimeters.

Convert inches to centimeters Problem Statement: Input a length in inches and convert it into centimeters (1 inch = 2.54 cm). Algorithm: Start Input the length in inches (inches). Convert the length to centimeters using the formula: centimeters=inches×2.54\text{centimeters} = \text{inches} \times 2.54centimeters=inches×2.54 Display the length in centimeters. End Explanation: To convert inches to centimeters, we … Read more

Calculate the area of a rectangle for a given breadth and length

Problem Statement: Given the length and breadth of a rectangle, calculate the area. Algorithm: Start Input the length (L) of the rectangle. Input the breadth (B) of the rectangle. Calculate the area using the formula: Area=L×B\text{Area} = L \times BArea=L×B Display the calculated area. End Explanation: The area of a rectangle is simply the product … Read more

Describe the steps involved in problem-solving.

Problem-solving typically involves the following steps: Understanding the problem: Clearly define the problem, its constraints, and requirements. Analyzing the problem: Break the problem into smaller, manageable parts and identify relevant information. Designing a solution: Develop possible solutions or approaches, considering resources, time, and feasibility. Implementing the solution: Put the chosen solution into action, ensuring to … Read more
