1. What is a strength of yours?
2. Write the code for Merge Sort.
3. Describe how to implement two stacks using a single array.
4. What is the effect on the exchange rate if the fiscal deficit increases?
5. Given an array, remove elements that appear consecutively for more than k times. Once removed, rejoin the left and right parts and remove again. Repeat until no such subarray exists. For example, given the array [1,1,2,2,3,3,3,2,2,4,1] and k=2, we remove [3,3,3] resulting in [1,1,2,2,2,2,4,1]. Then we remove [2,2,2,2] resulting in [1,1,4,1], which is the final array. Use a stack (push pair of element, current count, pop whenever count>k for any element).
