Algorithm Complexity

Time and Space Complexity (Big O Notation)

All algorithms have a complexity known as Big O Notation, the more complex an algorithm, the less efficient it gets as more data is introduced. Listed below are the Big-O complexities listed from best to worst:

  • O(1)
  • O(log n)
  • O(n)
  • O(n * log n)
  • O(n^2)
  • O(2^n)
  • O(n!)
