Some simple problems on Arrays

1. Given an array you are required to find the missing elements.
   Eg [1,2,3,5,6,8,9,10].The missing elements are 4 and 7
2. Write a program to reverse the elements in an array.
   Eg [1,2,3,4,5] will become [5,4,3,2,1]
3. Find the Kth largest and Kth smallest element in an array?
   Eg a=[1,2,3,4,4,5,6,7,8,9], k-3 will give (3,7)
4. Rotate an array. [1,2,3,4,5] to [5,1,2,3,4]
   
5. Find the max repeated element.
   [1,2,2,3,4,4,5,5,5,2,3,2]. Mode=2
6. Find the longest increasing sequence.
   [12,14,16,4,5,8,9,0,3], longest increasing =[4,5,8,9]
7. Write a program to perform Binary Search.
8. Write a program to merge two sorted arrays.
9. Write a program to merge 3 sorted arrays.
