Is a joke?

After 2 day i will have given exam can you help

About c++

In NIIt centre

After 2 day i will have given exam can you help

How can we?

Is a joke?

No...

After 2 day i will have given exam can you help

in 2 days you cannot learn C++

Java script is not a programming language

Yo mad

No, not me... The world is mad.

So what is it ??

Has anyone worked with libcurl?

I had a small issue

I'm doing a POST request with libcurl, the issue is that the data contents in the POST are also getting printed on the terminal

Samsung mock placement questions pretty easy lets se who come first

Has anyone worked with libcurl?

Don't use libcurl , use CPR library

I'm doing a POST request with libcurl, the issue is that the data contents in the POST are also getting printed on the terminal

The library doesn't print nothing by itself, so this must be your program

😁

lol

in 2 days you cannot learn C++

Why i want to revise it only

What is this?

I’m curious too

It's a competitive programming contest link. In the contest you're given 4 questions which you have to solve in 2 hours.

Pi's father, Danny, runs the Hackerville Zoo. He is moving to Rookieville and wants to take all of the zoo animals with him via ship. He is confused about how to arrange them because a few of the species cannot be kept together in the same cabin. There are n animals placed in a straight line. Each animal is identified by a unique number from 1 to n in order. There are m pairs (a[i], b[i]) which imply that animals a[i] and b[i] are enemies and should not be kept in the same cabin. Pi is good at solving problems and he came up with following challenge: count the number of different groups that do not contain any pair such that they are enemies. A group is defined as an interval (x, y) such that all animals in the range from x to y form a group. Determine the number of groups that can be formed according to the Pi's challenge. For example, given n = 3 animals and m = 3 pairs of enemies, a = [1, 2, 3] and b = [3, 3, 1], animal 1 is the enemy of animal 3, and animal 3 is the enemy of animals 1 and 2. Because 3 is an enemy of both 1 and 2, it must be in its own cabin. Animals 1 and 2 can be roomed together or separately. There are four possible groupings meeting the constraints: {1, 2} , {1}, {2}, {3}. Note that the intervals are along the original line of animals numbered consecutively from 1 to n, i.e. [1, 2, 3] in this case. The animals cannot be reordered and animals cannot be skipped, e.g. {2, 1} and {1, 3} are invalid intervals. Function Description Complete the function angryAnimals in the editor below. The function must return the number of groups that can be formed according to Pi's challenge. angryAnimals has the following parameters: n: an integer that denotes the number of unique animals a[a[0],...a[m-1]]: an array of integers b[b[0],...b[m-1]]: an array of integers

What logic to be used?

Which of the below one is faster in stl c++ maps or vector??

Which of the below one is faster in stl c++ maps or vector??

They are just completely different, you cannot compare them

Which of the below one is faster in stl c++ maps or vector??

You can compare only specific operations of them

Actually i want to store a pair values in container

So which one is better to use either vector with make_pair or map

Well.... And?

Please help make a c++ program if not multiple of 7 will use phi 3,14

Please help make a c++ program if not multiple of 7 will use phi 3,14

Nope. Think it for yourself. It needs for you, not for us. Ask here if you will have a trouble with code.

Yeah, you better start writing it, we will help

we will not write that code for you

Actually i want to store a pair values in container

If you need just a container of pairs, use std::vector< std::pair< int, double> >

If you need just a container of pairs, use std::vector< std::pair< int, double> >

Is it fast as compared to map for finding and erasing??

Is it fast as compared to map for finding and erasing??

No

So map is better to perfrom operations

??

So map is better to perfrom operations

which operations?

which operations?

Find, erase etc..

Find, erase etc..

OK it can be better, worse etc... 😂

Find, erase etc..

I see you just don't know what you want. In that case it doesn't matter which container to take.

Here i need to perform find the key and need to erase the value

Here i need to perform find the key and need to erase the value

What is the key?

If you need just a container of pairs, use std::vector< std::pair< int, double> >

Key is first

In pair or map

Key is first

Of what type is it?

String

String

then use std::map

Ok thanks

I want notes on boolean algebra
