Big O, Big Omega, or Ω, and Big Theta, or Θ, are notations used to express the computational complexity of an algorithm. Big O specifically describes the worst-case scenario, and can be used to describe the execution time required or the space used (e.g. O(n!) Using the rules, this can be simplified to O(n³). How do we use this chart? It is because the total time taken also depends on some external factors like the compiler used, processor’s speed, etc. Intuitively, the assertion "f(x) is o(g(x))" (read "f(x) is little-o of g(x)") means that g(x) grows much faster than f(x).
