1. Rewrite the above program to implement the selection sort algorithm recursively.

2. Extend the program written in Programming Problems 4 in such way that it would read the data from one fi le and write the sorted data into another fi le.

3. Write a program to search for a key value in an array of strings. The program should return the position of the key if it is found, otherwise it should return 1. Use the recursive version of a linear search algorithm.
