well apparently getch is removed from C/C++ library
is there any replacement?

std::cin.get()?
std::getchar()?

they both need Enter

Has ever getch been in stdlib?

Yeah
after recent search I realized it is just a compiler extension
so
is there any alternative for it?

Sockets is what you should be looking at.. Not IDEs

There is considerable amount of information about CS in general and C/C++ in specific in this site:

I think rose should add this to its note list
just to avoid the newbies nuances

Maybe ask Marie, Rose's elder sister to convince her

Code doesn't correspond screenshot you posted
Oh, I just edited the code, should I again put debugging output?

I do not understand why people are just doing such competitive programming things.
dj
how could i store results of permutation or combination of numbers on an array instead of printing them on C🤔
Cengizhan
Just??
Most of the questions are asked in here, from competitive programming stuff in recent days.

Arseny
Code is very sloppy
Arseny
No any checks when using C arrays
Ajay
Line 130, examine, which value passed to par and which size par is
Oh !! I changed the template for the LCA but forgot to change that there.
Big Thanks to you.
I couldn't find it because it was only showing me error on the function call in the screenshot that I provided you.

'Use the gdb/lldb, Luke'
gdb doesn't work properly on my mac version so I had to use valgrind

Because Google/Facebook/etc love competitive programmers
Arseny
lldb works just fine with clang
Ajay
I use gcc
Ajay
BTw, How did you find the error in there. I mean did you use breakpoint on that thing(normal way)?
Cengizhan

Yes ofc, pay more than 100k for writing silly Python codes for CI/CD environments.

Hey
Ajay
I'm not good at debugging things, that's a secondary reason why I use valgrind. I automatically catches SEGFAULT on just typing single command 😅

Easy:
Program received signal SIGSEGV, Segmentation fault.
0x0000555555555578 in query_up (x=500, y=1) at main.cpp:130
130 x = par[x][0]; //Then move to its parent, that means we changed chains

Recommend you to become good at this )

Btw i've no idea why you can face any troubles on mac with gcc/gdb
Ajay

Yes, I want to be seriously. I use vscode and use its debugging feature and so I've to keep clicking the step over sign to move the debugger to next breakpoint line. I'm mad.
Ajay

gcc was alright. But, I've gdb installed but I don't know sometime back it didn't work for me
Ajay
Arseny
"If you're on Sierra , that's expected. GDB isn't compatible with macOS Sierra , even the last release (7.12)."
Arseny
Arseny
But you can still use clang+lldb
Ajay
But you can still use clang+lldb
somewhere below the chat someone recommended me valgrind so I used it. 😅
Arseny
As you can see, normal debugger is better to find the trouble
Ajay
The best thing about valgrind is that I just had to run a single command and it pointed out all the respective segfault lines in the code, which uptill now I had no trouble fixing. But this really has questioned my belief.
Arseny
Debugger is pretty the same. I've just run gdb a.out and thats it
Ajay
As you can see, normal debugger is better to find the trouble
yes this particular case. It was easy. But, I think I need to learn debugging in valgrind rather than relying on that single command.
Arseny
Valgrind is not a debugger.
"Valgrind is an instrumentation framework for building dynamic analysis tools. "
Ajay

Oh !! I wish it was compatible with Mojave.
Ajay
BTW, can you recommend some debugger now that gdb doesn't work in my case?
Ajay
Valgrind is not a debugger.
"Valgrind is an instrumentation framework for building dynamic analysis tools. "
It was working for me like a debugger and so I assumed so 😂
Arseny
I've named it 3 or 4 times already ))) LLDB
