Here are the challenging C++ questions.

**********************************************************
(Pls. try to explain with either pseudo code or flowcharts)

1) Write a program that generates from the 
string "abcdefghijklmnopqrstuvwxyz{"  the following:		

                       a
                     bcb
                    cdedc
                   defgfed
                  efghihgfe
                 fghijkjihgf
                ghijklmlkjihg
               hijklmnonmlkjih
              ijklmnopqponmlkji
             jklmnopqrsrqponmlkj
            klmnopqrstutsrqponmlk
           lmnopqrstuvwvutsrqponml
          mnopqrstuvwxyxwvutsrqponm
         nopqrstuvwxyz{zyxwvutsrqpon

2) Write a program that concatenates two linked list objects of 
characters. The program should include function concatenate, which 
takes references to both list objects as arguments and concatenates 
the second list to the first list.

3) Write a program that merges two ordered list objects of integers 
into a single ordered list object of integers. Function merge should 
receive references to each of the list objects to be merged, and 
should return an object containing the merged list.

4) Write a program that inserts 25 random integers from 0 to 100 in 
order in a linked list object. The program should calculate the sum 
of the elements and the floating-point average of the elements.

5) Write a program that creates a linked list object of 10 characters 
and then creates a second list object containing a copy of the first 
list, but in reverse order.
