Jump to Post>How to calculate time complexity of any algorithm or program ....

The most common metric for calculating time complexity is Big O notation. This removes all constant factors so that the running time can be estimated in relation to N as N approaches infinity. In general you can think of …

Jump to PostIf you feel like reading this post slowly and carefully, it will describe what this notation _really_ means.

All functions have some kind of behavior as n grows towards infinity. For example, if f(n) = 1/n, then as n grows towards infinity, f(n) gets closer and closer to zero. …

Jump to Postsum=0;

for(i=0;i<n;i++)

for(j=0;j<i;j++)

sum++;

what is the actual running time of this code??Not positive, but it's probably theta (n * n!) = theta (n^2).

The reason I'd say that is because the outer loop is O(n) and the inner loop is always one less than whatever the value is …

I quite agree. Very strongly worded.

Jump to PostJust for my understanding, it means that the time complexity that we find using Big-Oh, Omega or Theta is not the actual execution time of the program?

Correct. The two are related, but not 1-to-1.

…Also which method will be best from the above two methods
