Problem Statement

What is Big O notation?

Step-by-Step Explanation

Big O notation describes how an algorithm's time or space grows as input size increases.

  1. Identify what the question is asking. In Algorithms, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
  2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
  3. Work one step at a time and keep units, signs, and restrictions visible.
  4. Check whether the answer makes sense in the original context.

Final Answer

Big O notation describes how an algorithm's time or space grows as input size increases. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
