In my data I have few hierarchy values - example address
Name -> Street -> City -> County -> State -> Country
The validation i need is, if a value in the above hierarchy is present then all the previous/higher order values should be present.
below is a valid case
Name -> Street -> City -> Stat...
See code below and my comment with questions:
pub fn factors(n: u64) -> Vec<u64> {
let mut m = n; // is it possible to convert n to a mutable type without using another variable?
let mut a:Vec<u64> = Vec::new();
while m % 2 == 0 {
a.push(2);
}
// in C we can just write...0
I'm new to C# and would appreciate any feedback you might have on the following doubly-linked list implementation, particularly WRT the following language features:
Exception handling
Debug.Assert
Null state attributes (e.g. MaybeNullWhen)
The Try pattern with out params
Test style with xunit

I assign the variable arrSize with zero ( int arrSize = 0; ) and in next line I take input from user for the variable arrSize. Let's suppose the user assigns 5 value to the variable.
When I execute my code, Cin is taking only 4 values instead of 5.
But when I only declare the variable ( int arrS...

This is my implementation of the divide-and-conquer Quicksort algorithm using the Lomuto partition scheme in C. This is part of a personal project and I'm following Linus Torvalds's coding style.
void swap(int *i, int *j)
{
int tmp = *i;
*i = *j;
*j = tmp;
}
int partition(int *arr, i...
let formData = new FormData()
formData.append("file", myfile)
console.log("uploading",formData,apiss)
const headers={

The core is this
// safer strcmp
static int safer_strcmp_ (
const size_t N,
const size_t M,
const char (*L)[N],
const char (*R)[M])
{
assert( 0 == ((*L)[N]) );
assert( 0 == ((*R)[M]) );
return strcmp(*L,*R) ;
}
Basically just checking if both strings are properly terminated...

In my real case I have a set of time series related to different IDs stored in a single DataFrame
Some are composed by 400 samples, some by 1000 samples, some by 2000.
They are stored in the same df and:
I would like to drop all the IDs made up of time series shorter than a custom length.
