2. You have to provide the challenge description and its input set
3. Winner must be submit output set
4. Everyone have to quote last challenge with his answer so that if answer is wrong others can try.
5. Each challenge must have to solve in between 1 day.
6. Anyone can post his own challenge but first he have to win previous challenge.

For example

Challenge Name : Find Me
Description : In this challenge you have to find all words from the input set.
Input set : {8,5,18,15},{4,15,7},{3,1,20}
