that's just binary search
Can you explain its time complexity

in BS, after every iteration, the size is divided by 2, so if the size is n, it gets repeatedly divided by 2
after like n1 number of division, the length becomes 1
thus length becomes (n/2)*n1 which equals to 1
put log on both side
and you get the value of n1
thus O(logn)

In binary search the worst case is not finding the value?

Any admin online please?

This is an urgent task that needs to be done today, there is a problem that keeps crashing our project and we need to point that out, we catch some logs by debugging it but it is not clear to us. We are looking forward to someone who can fix this.
The project is using C++ and also we need someone who has experience with WinSock.
This will be a paid task, if someone is interested give me a dm. Thank you

That's why I am asking if there is any admin available to ask permission if I can post this or not.

Question regarding CLion usage.
I have a project (C++) directory on my Linux machine.
I want to open this project directory in CLion such that it automatically creates a suitable CMakeList for it.
Does someone know to how to do that?
klimi
klimi
cmakelist is just a description of you project
Shahar
there is no such thing
So in case I have a project directory which contains headers and sources, also including other directories of header and sources, there is no a fast way to load it into a CMake?
klimi
i think the fastest
klimi
is to create new project so you get basic cmake
klimi
and then you add them to the description
klimi
well ya?
klimi
or i think that cmake has globbing... if you want to use that
Shahar
well ya?
and if i have also directories? i have to include them like directory/file1 directory/file2 directory/file3 etc.?
klimi
and if i have also directories? i have to include them like directory/file1 directory/file2 directory/file3 etc.?
yes... just like in makefile
klimi

klimi
and if i have also directories? i have to include them like directory/file1 directory/file2 directory/file3 etc.?
oh so apparently cmake has recursive glob
klimi
so you can use that
klimi
cmake_minimum_required(VERSION 3.0)
file(GLOB_RECURSE SOURCES RELATIVE ${CMAKE_SOURCE_DIR} "src/*.c")
add_executable(main ${SOURCES})

Anyone here have done pair programming? I want to know how does that help?
And is anyone interested!

How can I know where is my argv[1] placed on the stack in NASM? (I'm using IDA, which I'm liking it better than Ghidra for debugging and I'm learning to read NASM)

argv[1] is not necessarily placed on the stack. Depending on your ABI argv might be passed to main in the register rdx so argv[1] is at location [rdx+8]

I'm not seeing any [rdx+8] anywhere. This begins to make me feel uneasy...

can you share part of the disassembly? This heavily relies on the ABI with differs based on Architecture/Compiler/OS...

All my code. No headaches for anyone. I don't know how to pick this up. When I get to loc_5617B7F771EE at line 00005617B7F771FE, I don't know where does my input (aaaa) came from.

Again, this is another CTF challenge which was assigned to me, but I don't know how to handle them. I've never seen ASM in my entire life and today I learnt the basics for reading it. But anyway I can't figure out where did my parameter come from. 🤷🏻♂

cout << word << endl;

at starting you declared a,b,res as float type later in code u used int type (%d) format operator instead of float (%f) thats the reason : ) have a great day
