Although <bits/stdc++.h> is almost perfect for Cp, but still it is supported by GCC compiler only. As our repository is a learner-friendly repo, I would like you to include all the libraries/header files used.

Using char is a good but from 'C++' point of view, it will be better if we use the features of the language to a larger extent.
Like we have a string class inside CPP, and that can be used instead of char.
Using char is not wrong, but it is not a good practise as we are using 'modern C++'. Let's utilize the language properly.

Writing clean code is a great part of programming, not for CP contests, but for other human beings to understand your code.
Some points to be kept in mind,
- Use proper variable names, like we can use
array[]instead ofa. - We can use better names for
i&j.

Well as I have mentioned above, although scanf and printf are faster than the contemporary cin and cout, but I encourage you to use the later.
We are using C++ and let's use it's total feature. scanf and printf are also included in C programming language. Let's do something different in CPP.
I would like you to explore, getline(cin,str) function a little deeper.

instead of using long long int frequently in a bigger code, we can just use the powerful C++ feature.
I would like you to explore typedef and #define functionality of C++.
Also, can you make the code generic by using some Templates?
Hint : Use template<class T>

What about making the code modular? That will be easier for the learners to understand the I/O as well as the main algo.
Instead of including all the code inside the main function (which is a pretty bad standard in the industry), you may try to form some functions!
What about approaching the problem through the OOP functionalities of C++ ?
