I'm posting a solution for LeetCode's "Defanging an IP Address". If you'd like to review, please do. Thank you!
Problem
Given a valid (IPv4) IP address, return a defanged version of that IP address.
A defanged IP address replaces every period "." with "[.]".
Example 1:
Input: address = "1.1.1.1"

I was solving a task on CodeSignal here
You can view the task on the link I provided above.
Code
def check(matrix, num):
for arr in matrix:
for number in arr:
if number != num:
return True
return False

These extensions create an IObservable<T> that creates a long running task that can be cancelled. It runs the Func<T> after each interval of time and passes the result to OnNext() until the task is ended by the CancellationToken. The important thing here is that only one task is created with one ...
I apologize beforehand if this question does not follow the rules, or seems a bit silly. I really could not find any other place to put this. I will delete it if the case is the former.
Anyway, I want to name a data-attribute that performs an action when the element it is attached to is clicked. ...
I am learning dataframes with python and I am stuck on a strange behavior of errors when I type in the code below. As you can see I am getting errors for the pandas library internals. I am stumped on this code for days and have been stumped. I tried to get help from my online school and I have...
I've written the following function to produce n realizations of a CIR process for a given set of parameters:
def cir_simulations(alpha, mu, sigma, delta_t, n, num_sims):
x = np.reshape(np.array([mu] * num_sims), (-1, 1))
for i in range(0, n):
x = np.concatenate((x, np.reshape(x...
In Computer Systems: a Programmer's Perspective,
Unfortunately,
a number of commonly used library functions, including strcpy, strcat, and
sprintf, have the property that they can generate a byte sequence without being
given any indication of the size of the destination buffer [97]. Such conditi...
Introduction
bump is a command-line utility that I use to "bump" up the semantic version numbers present in any text file. It is written entirely in C and doesn't use malloc anywhere. Here's a table describing how the various bump levels work:
| Bump | Release | Result on 3.2.6 |

This is the follow-up question for A recursive_transform Function For Various Type Nested Iterable With std::variant Implementation in C++. As G. Sliepen's answer mentioned, leaving only recursively transforming operation for recursive_transform() may be a better idea. As the result, the implemen...
I want to make my calculator code shorter.
It is my code:

Ignore the commented out piece of code. The Hungarian Notation is a requirement for my university course so please don’t criticise t...
Recently I thought would what a program look like if all its characters that could become trigraphs became trigraphs for example
int main(void)
{
int array[10];
}
would become
int main(void)
??<
int array??(10??);
??>
. As a result I decided to make a program using ansi c89 that takes a...
Autodidact and inspired by David Beazley code (to improve my skills in Python) i would like to get your feed back on this Parser code.
NB: The lazy property let the code be computed only one time if used (https://github.com/dabeaz/python-cookbook/blob/master/src/8/lazily_computed_attributes/examp...
I have a requirement that ASP.NET background service should run Process method every day at 0:00 a.m.

A dataframe and a right-sided formula are given:
dat <- data.frame(
A = c("a", "b", "c"),
B = c("x", "y", "z"),
NotUsed = c(1, 2, 3)
)
frml <- ~ A + B + A:B
From them, I want to get this list:
# [[1]]
# [1] a b c
# Levels: a b c

# [[2]]
# [1] x y z
# Levels: x y z

# [[3]]

I've recently begun to teach myself to code. One simple project that I wanted to do was create a Caesar cipher that works well.
