Below is a question asked on the forum Stackoverflow.com. Provide a good and informational response to it like a helpful human would. Question: I want to use a structure like: struct node { char[10] tag; struct node *next;}; I want to use the above structure to create a doubly-linked list. Is that possible and if...
Yes, it's possible, but it's a dirty hack. It's called XOR linked list . ( https://en.wikipedia.org/wiki/XOR_linked_list ) Each node stores a XOR of next and prev as a uintptr_t. Here is an example: #include <cstddef>#include <iostream>struct Node{ int num; uintptr_t ptr;};int main(){ Node *arr[4]; // Here ...

I don't believe this is possible. The exec(2) system call always requires a filename or absolute path (the filename is always a char* ). posix_spawn also has similar requirements for a filename. The closest you could do is pipe the output into a named pipe and try executing from the pipe. That may work, although the ...

TL;DR: Use type annotations, they are awesome. For both Python and jedi it does not make a difference wheter you use docstrings or function annotations.

The order of a cycle is its length, and the order of a product of disjoint cycles is the l.c.m. of their orders, i.e. the l.c.m. of their lengths. Hence $\sigma$ has order $12$, so that $\sigma^{1000}=\sigma^{1000\bmod 12}=\sigma^4$. So $\sigma^{1000}\,$ has order $\dfrac{12}{4}=3$.

To begin with, a graph of a function $f$ is just a set $\{\langle x, f(x)\rangle\}$ . You probably wanted to ask whether the function $f(x)=\frac{x^2}{x}$ is continuous. The answer is yes: $f$ is continuous for all $x$ where it is defined . Note that $f(0)$ is not defined because of division by zero. However, $f$ admit...

It is indeed a -12V rail. Frequently used in audio circuits and for RS-232 driver circuits. There used to also be a -5V rail used by ISA cards. All a negative voltage is is a voltage rail which is at a lower potential than the 0V reference point we call ground. Remember that voltages are all relative - hence the name p...

It is easy to see that $f(x_n,y_n)$ converges to zero: let $\epsilon > 0$. For some $N$, $|x_i| < \epsilon$ and $y_i > 1$ for all $i \geq N$, so $|f(x_i,y_i)| < \ep...

Below is a question asked on the forum math.stackexchange.com. Provide a good and informational response to it like a helpful human would. Question: What is the intuition behind the definition of a differential of a function in differential geometry? i.e. $$df(p)(v_{p}) =v_{p} (f)(p) $$ where $v_{p} \in T_{p} M$ is a...
I like to think it this way: The "infinitesimal" perspective is not encoded in $df$ or in $v_p$, but in $f$ itself. This is because we define the derivations at a point $p$ not on smooth functions, but on the stalk of germs of smooth functions at $p$, i.e. on$$\mathcal{C}^{\infty}_p := \left\{ (f,U) : p \in U, U \text{...

It is all about decoupling and indirection .

You do not need to use BeginCollectionItem in order to achieve this.

Use Partial Views to display and update the list. One partial view to display and iterate ...

The parentheses are not needed because getAttribute automatically ...

The JIT debugger popup occurs when there's an unhandled exception. That is, an exception tunnels all the way up the stack to the root of any thread in the runtime. To avoid this, you can handle the AppDomain.CurrentDomain.UnhandledException event and just call Environment.Exit(1) to exit gracefully. This will handle a...

Your for-loop gets the map.entrySet and uses the iterator on it to work through the map entries (this version of the for-loop requires an Iterable, it gets the iterator from the Iterable). When you are using an iterator on a map, but remove things from the map without using that iterator, you get the ConcurrentModifica...

It's for two reasons. Well, actually just for one, but with two factors. A MOSFET can conduct in both directions when turned on, as it truly is just a resistive channel that is opened or closed.

You can get the syntax by using marker interfaces and extension methods. Prerequisite: the interfaces need to define the contract which is later used by the extension method. Basically the interface defines the contract for being able to "implement" a trait; ideally the class where you add the interface should already ...
