Algorithm | MCQs

Explanation

An algorithm is a step-by-step, well-defined list of instructions written in natural or simple language to solve a specific problem.

It serves as a blueprint for writing a program or creating a flowchart.

Explanation

Divide and Conquer works by dividing a problem into smaller sub-problems, solving them, and then combining the results.

Famous examples include Merge Sort and Quick Sort.

Explanation

A Brute Force Algorithm tries all possible solutions until it finds the correct one.

It is a straightforward but often time-consuming approach to problem-solving.

Explanation

Every algorithm begins with a start point and ends at a stop or termination point.

These ensure the algorithm has a defined flow and endpoint for execution.

Explanation

Flowcharts help visualize the logic and flow of an algorithm.

They are useful for spotting errors, inefficiencies, or missing steps before coding.

Explanation

Algorithm and Flowchart are tools used to:

• Define a problem
• Break it down into smaller steps
• Logically organize those steps
• Visually represent the process

They help to:

• Specify the problem completely and clearly
• Identify the steps needed to solve the problem
• Understand the logical flow of the solution
• Communicate the solution to others

Explanation

To determine the efficiency of an algorithm the time factor is measured by counting number of key operations

Explanation

Parallelogram represents the input and output symbols in a flowchart; it also represents data in general.

Explanation

The worst-case time complexity of quick sort occurs when the pivot element is always the smallest or largest element, leading to unbalanced partitions.

In such cases, the algorithm performs poorly with a time complexity of O(N²).

Explanation

Flowchart is a symbolic and diagrammatic representation of algorithm

A flowchart is nothing but a pictorial representation of an algorithm.
