Limits of SoloLearn Code Playground

Question

Hi, everybody! What does it mean: "Time limit exceeded", and "Memory limit exceeded" in SoloLearn Code Playground?

Answer 1

i just tested the memory limit. For me it seems to be 679 mb

Answer 2

sololearn executes your code on their own servers. Time and mem limits are introduced to prevent some programs from running too long or take up too much memory

From what i know, time limit is 5 seconds. Have to test what memory limit is

Answer 3

Data While trying to understand how new[] is working--just to understand allocator differences--I noticed that malloc() works into the several gigabytes range.
I also noticed, if you add a 1-second sleep right after your array allocation:

std::this_thread::sleep_for(std::chrono::seconds(1));

The highest number you can use is fixed. Similarly, if your class allocator allocates just 1 byte (vs 1024^2), there's another limit but it's not clearly proportional.

Knowing that new's supposed to allocate on the heap, I was still looking for some kind of stack exhaustion--I read somewhere that new with dynamic arrays was not preferred, but I haven't been able to determine why.

Answer 4

Beside Data said, this can happen randomatically (maybe for server problem)

Answer 5

it seems that memory limit differs from time to time. My code i posted earlier doesent run sometimes
