Structuring the Document - Hacker Rank Solution

The true problem here is to write function  from string. Let's write some assisting functions ,  and . They all will take some substring of the original string as a parameter. You can pass the substring itself, however, in order to save time and memory, two indices are recommended instead: the index of the original string where the substring begins and the index of the original string where the substring ends.

Variadic functions in C - Hacker Rank Solution

There is no built in way for a variadic function to know how many parameters have been passed. You don't have to use them all, but if you request too many, you will get garbage. 

Permutations of Strings - Hacker Rank Solution

Strings are usually ordered in lexicographical order. That means they are ordered by comparing their leftmost different characters.

Sorting Array of Strings - Hacker Rank Solution

You can use any sorting algorithm to sort strings in . Bubble sort is fast enough for the constraints in this problem. Let's look how should the bodies of the comparing functions look like.
