Is this a good approach to replace mysqli_num_rows?
$result = $db->query("SELECT * FROM users");
$result_set = $result->fetchAll();
$count = count($result_set);
if($count>0){
//if $count>0 show something special
while($row = array_shift($result_set)){
// my code
}

I don't know it is some design pattern for it or I can't do it in a different way the code looks like this:
Iteam iteam = itemRepository.findByNameAndNoAndCountryCodeAndCurrencyCode(name, countryCode, currencyCode);
if(item == null){
item = itemRepository.findByNameAndNoAndCountryCode...I am trying to solve Q645. While the logic used for my code seems to be appropriate, the code itself is way too slow for the large number required in this question. May I ask for suggestion(s) to improve my code's performance?
The question is as in the link: https://projecteuler.net/problem=645

My mergesort implementation currently takes a very long time. For a list with 1 million elements, it takes just over 130 seconds to get the answer. Could someone kindly have a look at my code and suggest what could I do do improve this, is there anything particular in my code that is taking sign...
I am using ASP.NET Core 3.1 and have been assigned a task to verify the count of changes done using SaveChanges().
It is expected that the developer should know how many records will be changed before-hand when SaveChanges() will be called.
To implement it, I have created an extension method for ...

I've just started a course that will require knowledge and experience with Python for future projects, which I don't have, so I thought I'd give it a go to familiarize myself with it and get some feedback. I got a decent summary of the language's main features from a 2 hour long overview video (h...
