1. Design a Program to store the details of a function call as a frame of data. Data in a frame should include function name, return type, arguments passed to a function. Maintain the starting address of every frame. Find out appropriate data structures to be used to solve the problem. If appropriate data structure found, implement the program, if not, justify your answer why the following data structure cannot be used to implement. (Analyze using Stack, Queue, Linked List (singly/doubly), Tree, Heap).


2. Consider a mouse trapped in a maze, trying to find the exit:
This mouse can only move right, left, down, or up—one step at a time. It applies the following procedure:

-> Try moving right, left, down, and up If a route beginning with any one of these fails,
-> Try a new route that starts in an untried direction.
The maze is implemented as a 2D array of char’s. 1 = wall,  0 = open, m = mouse’s initial position, e = exit (could be anywhere),  .(dot) = visited location. We assume the boundaries of the array are walls.
Find out appropriate data structure to be used to solve the problem. If appropriate data structure found, implement the program, if not, justify your answer why the following data structure cannot be used to implement. (Analyze using Stack, Queue, Linked List (singly/doubly), Tree, Heap).


3. Design an input restricted double ended queue for which only the operations removeleft, removeright, and insertleft are valid. And an output restricted double ended queue for which only removeleft, insertleft and insertright are valid.
Find out appropriate data structures to be used to solve the problem. If appropriate data structure found, implement the program, if not, justify your answer why the following data structure cannot be used to implement. (Analyze using Stack, Queue, Linked List (singly/doubly), Tree, Heap).


4. Design a C program to simulate a simple multiuser computer system as follows: Each user has unique ID and wishes to perform a number of transactions on the computer. Only one transaction may be processed by the computer at any given moment. Each input line represents a single user and contains user's ID followed by a starting time and a series of integers representing the duration of each of his or her transactions. The input is sorted by increasing starting time, and all the times and durations are in seconds. Assume a user does not request time for a transaction until the previous transaction is complete and computer accepts transactions based on First Come First Served basis. The program should simulate system and print a message containing user ID and time whenever a transaction begins and ends. At the end of simulation it should print the average waiting time for a transaction. ( Waiting time is amount of time between time that the transaction was requested and time it was started).
Find out appropriate data structures to be used to solve the problem. If appropriate data structure found, implement the program, if not, justify your answer why the following data structure cannot be used to implement. (Analyze using Stack, Queue, Linked List (singly/doubly), Tree, Heap, sorting algorithms). Justify your solution.


5. Design a program to implement a polynomial equation having 3 variables (x, y and z). Each node should represent a term and should contain the powers of x, y and z as well as coefficient of that term. Program should have following functions:
a. Add two such polynomials.
b. Multiply two such polynomials.
c. Take partial derivative of such polynomial with respect to any of its variables.
d. Evaluate such polynomial for given values of x, y and z.
e. Divide one such polynomial by another, creating a quotient polynomial.
f. Print the representation of such a polynomial.
Find out appropriate data structures to be used to solve the problem. If appropriate data structure found, implement the program, if not, justify your answer why the following data structure cannot be used to implement. (Analyze using Stack, Queue, Linked List (singly/doubly), Tree, Heap, sorting algorithms). Justify your solution.


6. Design a C program to perform following operations on a binary tree.
a. Accept a pointer to a node and return TRUE if that node is root of valid tree and FALSE     otherwise.
b. Accept a pointer to a node of a tree, and return level of that node in the tree.
c. Accept pointer to a tree and return a pointer to a new tree that is mirror image of the first       tree ( i.e. all left sub trees are now right subtrees and vice versa).
Find out appropriate data structures to be used to solve the problem. If appropriate data structure found, implement the program, if not, justify your answer why the following data structure cannot be used to implement. (Analyze using Stack, Queue, Linked List (singly/doubly), Tree, Heap, sorting algorithms). Justify your solution.
