Study Notes
Big O Notation Types
- O(1) represents constant time complexity, where the algorithm takes the same amount of time regardless of the input size.
- O(log n) represents logarithmic time complexity, often seen in algorithms that divide the problem size in half with each iteration, such as binary search.
- O(n) represents linear time complexity, often seen in algorithms that must examine every element in a collection, such as linear search.
- O(n log n) represents linear logarithmic time complexity.
- O(n^2) represents quadratic time complexity, often seen in algorithms that involve nested loops, such as bubble sort.
- O(n^3) represents cubic time complexity.
- O(2^n) represents exponential time complexity, often seen in algorithms that double the number of operations with each iteration, such as the naive recursive calculation of Fibonacci numbers.
- O(n!) represents factorial time complexity, often seen in algorithms that involve permutations or combinations of all elements in a collection, such as the traveling salesman problem.

Description
Learn about the various types of Big O notation, such as constant time complexity (O(1)), logarithmic time complexity (O(log n)), linear time complexity (O(n)), and more. Each type of Big O notation signifies a different growth rate in algorithm time complexity, with O(1) being the fastest and O(n!) being the slowest.
