Technical Interview Prep: Time and Space Complexity

Time and Space Complexity

Time and Space Complexity: What is it?

Coding problems can usually be solved in many ways. However, not all solutions are created equal.

Algorithms that are efficient and practical are essential to good software development. Your coding interviews will require you to compare the performance of different solutions.

Depending on the length of the input, the time complexity of a program determines how long the algorithm runs.

A time complexity measurement measures the amount of time it takes for an algorithm to execute as a function of the size of the input.

The space complexity refers to how much memory an algorithm needs to process that same input.
