[SOLVED] Cs2123 assignment 2: stacks and recursive programs

Implement a stack to store and remove strings that will be read from a file. The data file
contains a series of strings, one per line. Each string will contain 255 or fewer characters.
Whenever you read the string “pop”, this is a signal to pop your stack. Any other string
should be pushed onto your stack.The format of the data file is:.
.
.
poppop
etc.
To create the initial stack, use malloc to allocate enough space to store 10 strings. Keep
track of how many elements are in your stack. When you stack reaches capacity, your push
method needs to allocate more space to your stack before pushing the next element (add
space for another 10 strings). You can use realloc, or something else like malloc/copy/swap.
You do not ever need to shrink your stacks capacity.You are required to implement the following stack functions: push, pop, empty, and full.
• create returns a new empty stack.
• push takes a string parameter which is the value it pushes onto the stack. It may also
need to call realloc to expand the size of the stack before completing the push.
• pop returns the string that was removed from the stack.
• empty returns TRUE if the stack has no elements, otherwise FALSE.• full returns TRUE if the stack does not have any room left, otherwise FALSE.
Your program must print the assignment 2 and your name. Additionally, each time you
read “pop” (i.e., each time you receive a signal to pop the stack) you should print the # of
elements in the stack after popping and also print the string that is popped off the stack.You should also print a message every time your stack grows. For example, the program
might print the following:
Assignment 2 Problem 1 by
# elements after popping: 2 string popped: Be
# elements after popping: 1 string popped: sure
# elements after popping: 0 string popped: to
Stack capacity has grown from 10 elements to 20 elements
Continued on the back ,→The greatest common divisor (GCD) of two numbers is the largest number which divides
both of them (e.g., GCD(20, 15) = 5, GCD(20, 20) = 20, GCD(20, 9) = 1, . . .). We define
the GCD as follows:
GCD(x, y) = y if(y <= x and x%y == 0)
GCD(x, y) = GCD(y, x) if(x < y)
GCD(x, y) = GCD(y, x%y) otherwise
Use this definition to create a recursive algorithm for GCD.
In addition to this you should create an iterative algorithm for GCD. Since 1 ≤ GCD(x, y) ≤
minimum(x, y), you can test all of the values in this range using a while loop and return
the largest one.
Clearly, the results from both the recursive and iterative functions should be the same
otherwise something is wrong with one or both of your functions.
The main which will test your functions has been provided.

Answers to homework problems should be submitted as two C source code files, one file for
each problem. Archive and submit the files in Blackboard under Assignment 2.
Remember:
The program you submit should be the work of only you. Cheating will be
reported to judicial affairs. Both the copier and copiee will be held responsible.
