To add a bucket sort within a range and with particular number of buckets.
It will sort the unarranged array using bucket sort within that range only.
The first line will take the input of range and the no of buckets with space in hierarchical order.
The second line will take the input of the array to be sorted.
The output will give the sorted array of given array.

• The name of the file should be your github username. For example, mine would be praabi.py

Simple search element in an array.

The idea is to write a quiz maker(terminal based, mostly) which reads a set of
questions and their answers from a text file.

Possible Features

• If the user loses connection with the server, he should be able to connect
  back and have his answers already loaded.
• The server should be able to handle multiple participants at once.
• It should be almost JEE styled.
• More ideas are welcome!
