Feb 22, 2010 · You can think of O (1), O (n), O (logn), etc as classes or categories of growth. Some categories will take more time to do than others. These categories help give us a way of ordering the …

Oct 20, 2009 · O (1) - most cooking procedures are O (1), that is, it takes a constant amount of time even if there are more people to cook for (to a degree, because you could run out of space in your …

Mar 16, 2020 · I am preparing for software development interviews, I always faced the problem in distinguishing the difference between O(logn) and O(nLogn). Can anyone explain me with some …

Apr 29, 2012 · For the short answer, O (log n) is better than O (n) Now what exactly is O ( log n) ? Generally, when referring to big O notation, log n refers to the base-2 logarithm, (same way ln …

@Z3d4s the what steps 7-8 conversion is saying that n logn == log (n^n) and for showing the bound here you can say the first term is always greater than the second term you can check for any larger …

Jul 19, 2022 · By Stirling's approximation, log(n!) = n log(n) - n + O(log(n)) For large n, the right side is dominated by the term n log (n). That implies that O (log (n!)) = O (n log (n)). More formally, one …

I thought that $\\log(n!)$ would be $\\Omega(n \\log n )$, but I read somewhere that $\\log(n!) = O(n\\log n)$. Why?

Jan 8, 2016 · Log^2 (n) means that it's proportional to the log of the log for a problem of size n. Log (n)^2 means that it's proportional to the square of the log.

May 23, 2017 · O (log log n) terms can show up in a variety of different places, but there are typically two main routes that will arrive at this runtime. Shrinking by a Square Root As mentioned in the …

When comparing running times, it always helpful to compare them by using big values of n. For me, this helps build intuition about which function is slower In your case think of n = 10^10 and a = .5 …
