About the Big O Notation Calculator
A quick-reference and intuition-builder for algorithm time and space complexity.
What it is
The Big O Notation Calculator combines a searchable reference table of common algorithm and data structure complexities with a visual growth-rate chart and an operations estimator, so you can go from an abstract complexity class to a concrete sense of scale.
Features
Searchable reference table
Common operations with best/average/worst time and space complexity.
Growth-rate chart
Compare complexity classes on one chart, with a log-scale toggle.
Operations estimator
Enter a complexity class and N to see roughly how many operations it takes.
Toggleable series
Click any legend item to show or hide that complexity class on the chart.
