• diffhist Big O notation 22:59 +865 Mike Schwartz talk contribs (→2nd paragraph of this article: Add an {{efn}} template instance, to explain the meaning (in Computational complexity theory) of the terms "space" and "time", and to mention the consequences of the use of "Big O notation". →References and notes: add a sub-section, called "=== Notes ===", containing -- ONLY -- the template instance "{{Notelist}}". This is [needed] because of the addition of an {{efn}} tag in the text of (the second paragraph of the 'lede' section of) this article.)
