Clearing an array of defined element(s) - page 6

TheXpert:
One has 42 products, one has 6, one has 30. I'm afraid to imagine what an asshole there is inside with questions and answers like that

+1000500

[Konstantin Nikitin]

Реter Konow:

Sorry. It looks like the lines need to be reversed:

Have you tried a run? Even without a run, you can tell that it's not a problem to get out of the array when copying.

if(deleted)Arr[a1] = Arr[a1 + deleted];

Sergey Chalyshev:
+1000500

The circus has already left.

[Sergey Chalyshev]

Dmitry Fedoseev:

We have to get the basics right.

This is the main point,

you need the right (strategy) approach to solving the problem.

Dmitry Fedoseev:

Gone where? Like a circus?

I don't think he's going anywhere, and if he does, it won't be for long and he'll be back for sure.)

Just a second. Checking my solution. Just jotting down what came into my head. I'll check it out.

[Реter Konow]

The solution removes all the triples, but does not remove the digits at the end, because these digits should disappear when ArrayResize.

In other words, the last digits, are the ones that are not part of the modified array. I just didn't doan ArrayResize

What's there to talk about?

Perhaps how is it even more refined to smear the forum with shitcod.

Do you have a quicker solution?

Man, how I love to put down people fixated on the form rather than the content. It's a pleasure.)
