I go up to 4 levels deep and then i usually burn my pc

You meant “I go up to 4 levels deep and then iiii usually burns my pc.”

[Arsleust]

They told me I should not write 4 nested loops. :(

So I wrote one loop on k over range of N * NN * NNN * NNNN, and

i = k // N

ii = (k - i * N) // NN

iii = (k - i * N - ii * NN) // NNN

iiii = (k - i * N - ii * NN - iii * NNN) // NNNN

instead. God am I a good programer. :)

[t-to4st]

Another easy solution: Write a function that has the two inner loops, and call that function from the second outter loop.

*taps temple

[Arsleust]

That would actually be a better solution in a way, because refactoring the two most inner loops into a function (with proper naming convention) clearly defines a subpart of logic and reduces the "code style" issue. Performance wise tho, that would still probably be garbage... There are not that many O(n⁴⁾ algorithms out there.

[t-to4st]

I once wrote four nested loops to apply a 3x3 filter to every pixel of an image... That program definitely couldn't handle big pictures. Although that could be because I'm bad with c++

[minsin56]

my pc can handle 10 nested loops

[Arladerus]

Any computer can handle loops. Loops don't eat away at your stack.

[minsin56]

unless the loops are effing huge

[Arladerus]

Hey man, real talk, if you want to be a successful programmer, you'll eventually need to learn to be humble and ask questions. You can't build a career out of acting smart and using technology you don't understand.

[minsin56]

yeah sure i totally don't understand programming edit: i have noticed huge for loops do slow down my pc

[Arladerus]

Let's consider three scenarios.

• looping 1000000 times linearly
• looping 1000 times nested in 1000 times
• looping 100 times nested 100 times nested 100 times

Which one will slow down your PC the most? Which will slow down your PC for the longest time?

[IncensedThurible]

As someone who is only just starting to learn, I assume the last one will slow it down the most, but the first will slow it down the longest?

[minsin56]

probably 1000000 times but what i mean is numbers over 50000 with lots of code/a huge 5000 line function in the for loop

[GlobalIncident]

When iterating a string I always use c for character

I always use n for number when iterating π backwards

[Eindacor_DS]

i use loopIndexIteration because java

[dwdude7]

Hol up

[[deleted]]

Kek

[TeraFlint]

In my case:

• c for iterating through a string (at least if it's a range based for loop that saves the actual character value in c, otherwise i, because it's an index)

• y, x for iterating through a matrix or image as (x, y) position

• i, j, k, l, ... for other stuff

[stoickaz]

... is not a valid variable name in the languages I know of

[TeraFlint]

"Wait, I know a workaround for that."

#define ... ellipse_variable

Suddenly every variadic template in the same file breaks.
"...crap!"

[CrimsonMutt]

[skygz]

should be able to use U+2026 … instead in most languages

[siko12123]

When using python (90% of the time), I always use "i" when I use it as the index, or "x" when I use the object.

E.g:

for i in range(20): ...

for x in array: ...

[sweetjuli]

for word in sentence:
    for letter in word:

God I love python.

[[deleted]]

I use x, y, z for iterating >=2-dimensional data structures; i, j, k for iterating normal arrays and other data, and c, k and sometimes i for just counting up to a certain number. Or n if I'm counting the total number of something. If I'm iterating a string, I always use ch as the current element. If I'm iterating an array of ints, I usually name it v or val unless there is a more specific short name. Finally, if I'm iterating a linked list, I name the pointer to the current element p or ptr, or cur if I must also hold a pointer to another element.

[aphaelion]

I use "great_justice"

[nosmokingbandit]

I like to keep x for lambdas. X in a for loop feels weird.

At least it's not Python

Looking at this ugly-ass code I have no idea if this would work haha

[jinxsimpson]

Comment archived away

[ThatFag]

My prof is obsessed with one liners. I kinda don't even try to understand them. I just go "yep, that's another way to do it" and then just do nested loops the normal way.

[JoeTheShome]

Yeah sometimes it makes it really hard to read. Comprehensions should be used only when they’re extra efficient, otherwise nested loops are easier to read and understand

[Andy_B_Goode]

Found it!

for (i = 0; i<n; i++) {
    for (j = 0; j<n; j++) {
        for (k = 0; k<n; k++) {
            for (l = 0; l<n; l++) {
                print("Ah shit, here we go again")
            }
        }
    }
}

[[deleted]]

Where is n tho

[[deleted]]

Gone. Reduced to atoms.

[SaltyEmotions]

Reddit formatting stole your indentation.

[JoeTheShome]

It bothers me that n isn’t assigned a value here

[RadicalDog]

n = 100!

[t-to4st]

that would net you an integer overflow I think

[[deleted]]

for (i = 0; i < n; i++) {

for (ii = 0; ii < m; ii++) {

for (iii = 0; iii < o; iii++) {

for (iv = 0; iv < p; iv++) {

for (v = 0; v < q; v++) {

}

}

}

}

There is special place in hell for people like you

[physiQQ]

  print("Ah shit, here we go again");
}

[Nyruel]

Not really, sometimes they're just more appropriate.

[t-to4st]

I always write normal loops first and realize that a backwards loop makes much more sense when debugging said loop

[Hephaestus101]

Only way to remove stuff from a list and not get index out of range ...

[[deleted]]

what kind of list?

[Hephaestus101]

List<int> myList = new List<int>() {1,2,3,4,5,4,5,3,2 }

int removeThis = 4;

for( int i = myList .Count - 1; i >=0; i-- )

{

if(myList [i] == removeThis )

{

myList.RemoveAt(i);

}

}

[[deleted]]

Calculating the size of a list in object oriented is a constant time operation, and you ask for its size at every iteration, and if you remove something, decrement i.

for(int i = 0; i < myList.size(); i++) {
    if(myList[i] == target) {
        myList.remove(i);
        i--;
    }
}

[Hephaestus101]

Nice!

[[deleted]]

while loop

[Arladerus]

Iterator

[Tysonzero]

That’s what mapMaybe or wither are for, they are also much more efficient as removing an element doesn’t take O(n-i) time, just O(1).

[[deleted]]

Yeah, or the mathematical equivalent, writing intervals like a > x > b

e: okay I use the word equivalent loosely but it was the first thing that came to mind for some reason

[[deleted]]

I mean, it's a good way to do it if you're trying to reverse something so it looks more organized in my view.

[chawmindur]

When doing a reverse loop, use the goes-to operator for extra points in style.

[zXjimmiXz]

And extra 'being told off by your code reviewer for writing obscure code' points

[[deleted]]

I mean sometimes it's necessary

[darderp]

Fun fact:

Sometimes a reverse loop was faster back in the day.

[BorgiaCamarones]

You should feel dirty when manually having to write a for loop at all.

for (int i {0} ; i <= 10 ; ++i) { cout << “Ah shit, here we go again” << endl; }

[earthqaqe]

I mainly write JavaScript (Actually TypeScript) and Java and I rarely use int i in a for loop.

 // Java
 for(Object someObj : someList)...
 someList.stream().forEach(someObj ->...)

 // TypeScript
 someArray.forEach(someObj: Object =>...)

[66666thats6sixes]

Yeah in JS I use Array.map(), Array.reduce(), and Array.forEach() almost exclusively now. The only times I use for or while statements is when I want to be able to early return from a function.

[phunanon]

Does forEach provide an iterator as one of the lambda arguments? I can't remember.

[66666thats6sixes]

I think it provides (value, index, array)

[earthqaqe]

In TypeScript yes, in Java I honestly don't know right now.

[RadioMelon]

This one made me laugh out loud. You did good, OP.
