[sarahg500]

• emphasize more in the first part that Big O is important for run time
• in the second half, Big O, Big Theta, Big Omega should be clearer

Is it the time complexity - concept.md? There is no md file called Big O concept.

If it is the case, then there is no big theta and big omega in this md file.

There is a Big O concept- should be the first one in the concepts file under Module4_Labs
