How can building a heap be O(n) time complexity?
...s buried in this topic:
How do you implement buildHeap so it runs in O(n) time?
How do you show that buildHeap runs in O(n) time when implemented correctly?
Why doesn't that same logic work to make heap sort run in O(n) time rather than O(n log n)?
How do you implement buildHeap so it runs in O(n)...
std::wstring VS std::string
...
Windows actually uses UTF-16 and have been for quite some time, older versions of Windows did use UCS-2 but this is not the case any longer. My only issue here is the conclusion that std::wstring should be used on Windows because it's a better fit for the Unicode Windows API which I...
Is there a way to instantiate objects from a string holding their class name?
...f. C++ has no mechanism to create objects whose types are determined at runtime. You can use a map to do that mapping yourself, though:
template<typename T> Base * createInstance() { return new T; }
typedef std::map<std::string, Base*(*)()> map_type;
map_type map;
map["DerivedA"] = &a...
How to detect if my shell script is running through a pipe?
...
@josch I wish I could! I don't presently have time to do a deeper dive into this. But try any of your suggested approaches with both ssh -t and ssh -T - you'll see that approaches that work using ssh -t don't work using ssh -T.

How to run only one local test class on Gradle
...t class. As I'm building a test case, I typically run a single method at a time to make it easier to focus on just the output I need to debug, then run the entire test case at the end.

Pointer to pointer clarification
...means the same as "assign to ip1". Since you didn't assign to ipp a second time, it didn't change!
If you wanted to change ipp then you'll have to actually assign to ipp:
ipp = &ip2;
for instance.

Add Keypair to existing EC2 instance
...
Now, one your local machine chmod john to 600.
$ chmod 600 john
Step 5: time to test your key:
$ ssh -i john john@111.111.11.111
So, in this manner, you can setup multiple users to use one EC2 instance!!

In pure functional languages, is there an algorithm to get the inverse function?
...: ls)
Since this first B0 in the output must have come after some finite time, we have an upper bound n on both the depth to which inv had actually evaluated our test input to obtain this result, as well as the number of times it can have called f. Define now a family of functions
g j (B1 : B0 : ...
How can I convert a comma-separated string to an array?
