In this c++ assignment, add an undo feature to a list of strings.
Here's a working class called Stringlist that implements a simple string list as a dynamic array. Stringlist_test.cpp has tests for all the methods in Stringlist.
Stringlist has one unimplemented method:
// Undoes the last operation that modified the list. Returns true if a
// change was undone, false otherwise.
//
bool undo()
{
cout << "Stringlist::undo: not yet implemented\n";
return false;
}
Your job is to implement undo, thus making Stringlist an undoable list.
Your implementation must follow these rules:
Do not delete any methods, or change the signatures of any methods, in Stringlist. You can change the implementation of existing methods if necessary. But they should still work the same way: your finished version of Stringlist with undo implement must still pass all the tests in Stringlist_test.cpp.
You can add other helper methods (public or private), functions, and classes/structs to Stringlist.h if you need them.
You must implement undo() using a private stack that is accessible only inside the Stringlist class. Implement the stack yourself as a linked list. Do not use arrays, vectors, or any other data structure for your stack.
Do not use any other #includes or #pragmas in Stringlist.h other than the ones already there.
When it's done, you'll be able to write code like this:
#include "Stringlist.h"
#include
using namespace std;
int main() {
Stringlist lst;
cout << lst << endl; // {}
lst.insert_back("one");
lst.insert_back("two");
lst.insert_back("three");
cout << lst << endl; // {"one", "two", "three"}
lst.undo();
cout << lst << endl; // {"one", "two"}
lst.undo();
cout << lst << endl; // {"one"}
lst.undo();
cout << lst << endl; // {}
}
Designing the Undo Stack
As mentioned above, you must implement undo() using at least one private stack implemented as a linked list inside the Stringlist class. You can modify Stringlist only as described at the start of this assignment.
examples of how specific methods should work.
Undoing insert_before
In code:
// lst == {"dog", "cat", "tree"}
lst.insert_before(3, "hat");
// lst == {"dog", "cat", "tree", "hat"}
lst.undo();
// lst == {"dog", "cat", "tree"}
lst.insert_before(1, "shoe");
// lst == {"dog", "shoe", "cat", "tree"}
lst.undo();
// lst == {"dog", "cat", "tree"}
Undoing set
For set, suppose that lst is {"yellow", "green", "red", "orange"}, and so lst.get(2) returns "red". If you call lst.set(2, "cow"), then you should push the operation set location 2 to "red" onto the undo stack, and then over-write location 2 with "cow".
In code:
// lst == {"yellow", "green", "red", "orange"}
lst.set(2, "cow");
// lst == {"yellow", "green", "cow", "orange"}
lst.undo();
// lst == {"yellow", "green", "red", "orange"}
Undoing remove_at
For remove_at
In code:
// lst == {"dog", "cat", "tree"}
lst.remove_at(1);
// lst == {"dog", "tree"}
lst.undo();
// lst == {"dog", "cat", "tree"}
Undoing operator=
For operator=,
In code:
// lst1 == {"dog", "cat", "tree"}
// lst2 == {"yellow", "green", "red", "orange"}
lst1 = lst2;
// lst1 == {"yellow", "green", "red", "orange"}
// lst2 == {"yellow", "green", "red", "orange"}
lst1.undo();
// lst1 == {"dog", "cat", "tree"}
// lst2 == {"yellow", "green", "red", "orange"}
As this shows, when you undo operator=, the entire list of strings is restored in one call to undo().
Important notes:
If lst1 and lst2 are different objects, then when lst2 is assigned to lst1 just the underlying string array of lst2 is copied to lst1. The lst1 undo stack is updated so that it can undo the assignment. The undo stack of lst2 is not copied, and lst2 is not modified in any away.
Self-assignment is when you assign a list to itself, e.g. lst1 = lst1;. In this case, nothing happens to lst1. Both its string data and undo stack are left as-is.
Undoing remove_all
For remove_all,
In code:
// lst == {"dog", "cat", "tree"}
lst.remove_all();
// lst == {}
lst.undo();
// lst == {"dog", "cat", "tree"}
Note that it should work the same way when lst is empty:
// lst == {}
lst.remove_all();
// lst == {}
lst.undo();
// lst == {}
Undoing Other Methods
undo() should undoall the other methods in Stringlist that are marked as "undoable" in the source code comments.
As mentioned above, undo() is not undoable. There is no "re-do" feature in this assignment.
Each method in Stringlist.h marked "undoable" should work correctly with undo(). This also includes the correct behaviour for the Stringlist copy constructor (which should not copy the undo stack).
The markers tests should run correctly, including with no memory leaks according to valgrind.
To implement the undo feature in the Stringlist class, you will need to modify the existing class and add a private stack implemented as a linked list. Here are the steps to follow:
How to write the program code1. In the Stringlist class in Stringlist.h, add a private struct called `UndoNode` to represent each node in the undo stack. Each node should store the necessary information to undo an operation (e.g., the method name, the arguments, and any other relevant data).
```cpp
private:
struct UndoNode {
std::string method; // The method name
// Add other necessary data for the specific method being undone
// ...
UndoNode* next; // Pointer to the next node in the stack
UndoNode(const std::string& m) : method(m), next(nullptr) {}
};
```
2. Add a private member variable `undoStack` of type `UndoNode*` to the Stringlist class to keep track of the undo stack.
```cpp
private:
// Other private member variables
UndoNode* undoStack;
```
3. Modify the undoable methods in the Stringlist class to push the necessary information onto the undo stack before performing the operation. For example, in the `insert_before` method:
```cpp
void insert_before(size_t index, const std::string& str) {
// Push the operation onto the undo stack
UndoNode* undoNode = new UndoNode("insert_before");
// Add necessary data to the undoNode (e.g., index and str)
// ...
// Perform the actual operation
// ...
// Add the undoNode to the top of the stack
undoNode->next = undoStack;
undoStack = undoNode;
}
```
4. Implement the `undo` method to pop the top node from the undo stack and perform the undo operation based on the stored information. You will need to handle each operation individually in the `undo` method.
```cpp
bool undo() {
if (undoStack == nullptr) {
std::cout << "Undo stack is empty." << std::endl;
return false;
}
UndoNode* undoNode = undoStack;
undoStack = undoStack->next;
// Perform the undo operation based on the stored information in undoNode
if (undoNode->method == "insert_before") {
// Undo the insert_before operation
// ...
} else if (undoNode->method == "set") {
// Undo the set operation
// ...
}
// Handle other operations...
delete undoNode;
return true;
}
```
Remember to handle memory deallocation appropriately and update other methods marked as "undoable" accordingly.

Memory is very important in computers, the reasons for this, technical strategies that can be taken to increase computer performance cost-effectively, and why the strategies are successful.
Memory plays a significant role in the functioning of computers, since, without it the computer cannot run applications or perform other operations.
When the computer is turned on, it loads the operating system from storage into memory and the operating system allocates memory to other programs.
Memory is crucial because it allows the computer to access data rapidly and keeps the computer running quickly.
Technical strategies to improve computer performance cost-effectively include upgrading the memory, optimizing the software, and reducing the number of applications running.
Upgrading the memory is the most cost-effective way to increase computer performance, as it allows the computer to access data more quickly and improves multitasking.
Optimizing software can improve the efficiency of the operating system and applications, and reducing the number of applications running reduces the burden on the computer's memory and processor.
These strategies are successful because they improve the computer's ability to access and process data quickly and efficiently, resulting in faster performance.

The half-life of a decaying radioactive isotope is the time it takes for half of the original mass of the isotope to decay.
If the mass (in grams) of a particular radioactive sample is given by M(t)=30e^(-0.05t) where t is in years, what is the half-life of that isotope?
Round your answer to 2 decimal places. Do not include units.
To find the half-life of the isotope, we need to determine the value of t when the mass M(t) is equal to half of the original mass. By setting M(t) = 30e^(-0.05t) equal to half the original mass (15 grams) and solving for t, we can find the half-life.
To find the half-life of the isotope, we set the mass M(t) equal to half of the original mass. In this case, the original mass is 30 grams, so we have30e^(-0.05t) = 15Next, we divide both sides of the equation by 30 to isolate the exponential term:e^(-0.05t) = 0.5To eliminate the exponential, we take the natural logarithm (ln) of both sides:ln(e^(-0.05t)) = ln(0.5)Using the property of logarithms, ln(e^(-0.05t)) simplifies to -0.05t:-0.05t = ln(0.5)Finally, we solve for t by dividing both sides of the equation by -0.05:t = ln(0.5) / -0.05Using a calculator, we find t ≈ 13.86 years.Therefore, the half-life of the isotope is approximately 13.86 years.For more such question on isotope
