An algorithm is a set of unambiguous step-by-step instructions for solving a problem using a finite amount of time and data, while pseudocode expresses algorithms using a mix of English and formatting to explicitly show solution steps without strict grammar rules or case sensitivity.

1. Algorithm vs Pseudocode

2. Algorithm
A set of unambiguous instructions for solving a problem or subproblem
in a finite amount of time using a finite amount of data
Why must instructions be unambiguous?
Why must time and data be finite?

3. Pseudocode
• A way of expressing algorithms that uses a mixture of English
phrases and indention to make the steps in the solution
explicit
• There are no grammar rules in pseudocode
• Pseudocode is not case sensitive
