Fastest way to iterate over all the chars in a String
... as byte[] by default.
SECOND UPDATE: As of 2016-10-25, on my AMDx64 8core and source 1.8, there is no difference between using 'charAt' and field access. It appears that the jvm is sufficiently optimized to inline and streamline any 'string.charAt(n)' calls.
THIRD UPDATE: As of 2020-09-07, on my Ry...
Hashset vs Treeset
I've always loved trees, that nice O(n*log(n)) and the tidiness of them. However, every software engineer I've ever known has asked me pointedly why I would use a TreeSet . From a CS background, I don't think it matters all that much which you use, and I don't care to mess around with hash functi...
How to find all positions of the maximum value in a list?
... 0 for this is 2n, the list is iterated through 2x, once to determine max, and another time to find the positions of the max. A for loop that tracks the current max and its position might be more efficient for really long lists.

Interview question: Check if one string is a rotation of other string [closed]
...
First make sure s1 and s2 are of the same length. Then check to see if s2 is a substring of s1 concatenated with s1:
algorithm checkRotation(string s1, string s2)
if( len(s1) != len(s2))
return false
if( substring(s2,concat(s1,s1))

It provides commands to support debugging and exploit development similar to the ones from PEDA, and better display (although this is not the main focus of the project). The software is still under development, and has not been properly rele...
Algorithm to find Largest prime factor of a number
...factorisation. It makes use of the identity N = (a + b)(a - b) = a^2 - b^2 and is easy to understand and implement. Unfortunately it's not very fast in general.
The best known method for factoring numbers up to 100 digits long is the Quadratic sieve. As a bonus, part of the algorithm is easily done...
How do I adjust the anchor point of a CALayer, when Auto Layout is being used?
...at in layoutSubviews the runtime comes dashing through all the constraints and setting the frames of all the views accordingly.
In other words, the constraints are not magic; they are just a to-do list. layoutSubviews is where the to-do list gets done. And it does it by setting frames.
I can't hel...

Conveniently Declaring Compile-Time Strings in C++
Being able to create and manipulate strings during compile-time in C++ has several useful applications. Although it is possible to create compile-time strings in C++, the process is very cumbersome, as the string needs to be declared as a variadic sequence of characters, e.g.
