Code Forces Problem Way Too Long Words
Also break the problem into separate methods like for 1. Parsing int where (1 <= int <= 100) 2. Parsing string validating they are not null or empty or whitespace and length <= 100. 3. Solving problem (here abbreviating words whose length >10)

I have a huge exam next week
It's just fear. 1. Chill out 2. You'll definitely gonna repeat. That will give you more experience. But do try your best to clear. 3. First prepare what you've already touched. 4. And just take your best shot.

Ok, so Char* in String(Char*) is pointer of first element of character array. If I understand right. Hence, both way declaring and initializing pointer works 
unsafe
        {
            char[] cArray = {'a','r','r','a','y'};

            fixed(char* ptr = cArray)
            {
                string s = new string(ptr);
                // Do stuff with string s
            }

            fixed(char* ptr = &cArray[0])
            {
                string s = new string(ptr);
                // Do stuff with string s
            }
        }
unsafe
        {
            char[] cArray = {'a','r','r','a','y'};

            fixed(char* ptr = cArray)
            {
                string s = new string(ptr);
                // Do stuff with string s
            }

            fixed(char* ptr = &cArray[0])
            {
                string s = new string(ptr);
                // Do stuff with string s
            }
        }
Thanks, the link was very helpful 🙂

QuickSort implementation gets me an out-of-range error
Everything is alright at least for me. The problem was in MakePivot() method. I think it was mixing values with there index. I completely rewrote the method MakePivot(). Here's the whole program for reference: https://paste.mod.gg/ppikrzcciypc/0 Followed the algorithm mentioned in wikipedia: https://en.wikipedia.org/wiki/Quicksort This image sums the whole algorithm: https://en.wikipedia.org/wiki/File:Quicksort-diagram.svg

https://youtu.be/y-GNaO6OhdM?si=w5dHQkexUnS2HoUV I agree that debugging in VS Code is little weird. This is what I do. Making video on how to debug in VS Code took me more time than actually debugging the code.

How to install dotnet runtime and sdks on debian virtual machine?
Thanks I end up manually downloading it from https://dotnet.microsoft.com/en-us/download/dotnet/8.0 I works as intended but I am not able to set it as system wide environment variable. I tried adding its path to /etc/environment like this DOTNET_ROOT="/home/user/directory_where_i_have_downloaded_dotnet_runtime" But it still shows dotnet: command not found if I type dotnet in any directory other than the one where it is present.

Is Merge Sort implementation wrong in Wikipedia?
I was thinking of copying array B to A after sorting to then use the new partly sorted array A in further steps of recursion instead of using completely unsorted A each time. 
void TopDownMerge(B[], iBegin, iMiddle, iEnd, A[])
{
    // Sort B

    // Then copy B to A
}
void TopDownMerge(B[], iBegin, iMiddle, iEnd, A[])
{
    // Sort B

    // Then copy B to A
}
