Problem 1. Create a static method that takes an array of integers and a target value as arguments and returns an array with the indices of two array elements such that they add up to the specified target value. Write a driver class to demonstrate that your method works. You may assume that each input to the method would have exactly one solution.

Example: Assuming that input is the array [5, 19, 7, 21] and the target value 12 your program should output: [0, 2], since 5 + 7 = 12.

Problem 2. Modify your program to deal with the case where no solution exists and the case where multiple solutions exist.
