1. Extend the java Project MergeTwoLists by ensuring the lists being merged are sorted and so is the merged list.

2. Write Two Unit Tests to check the merging of unsorted lists resulting in a merged sorted list.

I First Unit Test having first list having 5 elements in reverse order and second list with a single element larger than all elements in the first list.

II Second Unit Test having first list as [5, -13, 7, 11] and second list as [12, -3, 0]
