Guidelines for writing pseudocode:

1. C/Java/Python instructions are fine. But do not write object-oriented additions. Do not declare or use any class. Declare only procedures (if necessary) and explain in words what each procedure does, and what is the use of each parameter.

2. One instruction per line

3. Match the brackets with a horizontal line

4. Number your lines

5. Write down if your array is indexed 0...n1 or 1...n.

6. If you decide to use procedures/functions/methods from the class (such as, say, DELETE- MAX(S) for S a max-heap), explain clearly what they do and in what running time. Explain the data structures, if any.

Question: Suppose that you have a black-box worst-case linear-time median subroutine. Give a simple, linear-time algorithm that, given an array A[1..n] and a positive integer i n finds the i^th smallest element of A. Present pseudocode using procedures from the textbook or notes; give complete specifications and state the running time of the procedure in terms of its parameters.
