While answering to this question a debate began in comments about complexity of QuickSort. What I remember from my university time is that QuickSort is O(n^2) in worst case, O(n log(n)) in average cas
What\'s the big O for JavaScript\'s array access when used as a hash? For example, var x= []; for(var i=0; i<100000; i++){
Can some help me with a function which is Big O(1) but not Ω(1) and the other way around? Some explanation would greatly he开发者_JAVA百科lp.Big-O means <= and big Omega means >=, so a function th
I have come across the term O(log* N) in a book I\'m reading on data structures.What does lo开发者_如何学Cg* mean?I cannot find it on Google, and WolframAlpha doesn\'t understand it either.It\'s calle
I know that the relation n = Big-O(1) is false. But if we use induction involving Big-O it can be proved. But the fallacy is we cannot induct Big-O. But my question is how we can disprove the relation
The recursive function defined as so: function factrec($x) { if($x <= 1) { return $x; } else { return $x * factrec($x - 1);
If I have an array of 1 million 开发者_C百科integers. Summing it up is considered O(n) because I have to perfom n-1 add operations.
When reasoning about runtime cost in a garbage collected language, what is the cost of a statement such as myList = null; in terms of \'n\' (the number of elements in the list)?For sake o开发者_如何转
I have a bit of code and need to write a recurrence relation for it.The code simply calculates 2 raised to the nth power.
I am trying to work out a few guesses on algorithm complexity, but every time I attempt to guess using an exponential time, my guess/verify method seems to fail. I am sure I am doing something absurdl
