In an ancient land, the beautiful princess Eve had many suitors. She decided on the
following procedure to determine which suitor she would marry. First, all of the suitors
would be lined up one after the other and assigned numbers. The first suitor would be
number 1, the second number 2, and so on up to the last suitor, number n. Starting at
the first suitor, she would then count three suitors down the line (because of the three
letters in her name) and the third suitor would be eliminated from winning her hand and
removed from the line. Eve would then continue, counting three more suitors, and
eliminating every third suitor. When she reached the end of the line, she would continue
counting from the beginning. For example, if there were six suitors, then the elimination
process would proceed as follows:
123456 Initial list of suitors, start counting from 1
12456 Suitor 3 eliminated, continue counting from 4
1245 Suitor 6 eliminated, continue counting from 1
125 Suitor 4 eliminated, continue counting from 5
15 Suitor 2 eliminated, continue counting from 5
1 Suitor 5 eliminated, 1 is the lucky winner
Write a program that creates a circular linked list of nodes to determine which position
you should stand in to marry the princess if there are n suitors. Your program should
simulate the elimination process by deleting the node that corresponds to the suitor that
is eliminated for each step in the process. Be careful that you do not leave any memory
leaks.

*Previous we solved this question using vector, now use the linkedList instead of
vector*

Following is the program using vector for your reference.

#include <iostream>
#include <string>
#include <vector>
using namespace std;

int main(){
int n;
cout<<"Enter the number of suitor: ";
cin>>n;
vector<int> v;
for(int i=1;i<=n;i++)
v.push_back(i);
int index = 0;
while(v.size()>1){
index = index + 2;

if(index >= v.size()) index = index % v.size();
v.erase(v.begin()+index);
for(int i=0;i<v.size();i++)
cout<<v[i]<<" ";
cout<<endl;
}
cout<<"the final one is "<<v[0]<<endl;
}

Follow-up Question

There's a lot of errors

### C++ Compilation Error Analysis

The following output illustrates common compilation errors that can occur in C++ programming. Understanding these errors can help both novice and experienced programmers debug their code more efficiently.

#### Error Messages:

1. **main.cpp:9:20: error: expected unqualified-id**
```cpp
list<int>1;
^
```
- **Explanation:** The compiler expected an identifier but found a digit. This is likely due to a typo where a space is required between `list<int>` and the identifier.

2. **main.cpp:23:14: error: assigning to 'int' from incompatible type 'int (const char *) noexcept (true)'**
```cpp
i= remove;
^~~~~~~~~~
```
- **Explanation:** The code attempts to assign a function pointer to an integer variable, which is incompatible. The function `remove` might need to be called appropriately if intended.

3. **main.cpp:25:36: error: invalid suffix 'begin' on floating constant**
```cpp
list<int>::iterator it=1.begin();
^~~
```
- **Explanation:** The syntax `1.begin()` incorrectly treats `1` as an object. This is likely a mistake where `list<int>` was intended instead of `1`.

4. **main.cpp:27:19: error: invalid suffix 'size' on floating constant**
```cpp
while(1.size()>1) {
^~~
```
- **Explanation:** Similar to the previous error, `1.size()` is treated incorrectly, where `list` or another iterable type should be used.

5. **main.cpp:31:45: error: expected ';' at end of declaration**
```cpp
list<int>::iterator it2=it++
^
```
- **Explanation:** The statement is missing a semicolon `;` at the end.

6. **main.cpp:35:19: error: assigning to 'int' from incompatible type 'int (const char *) noexcept (true)'**
```cpp
i=remove;
^~~~~~~~~~
```
- **Explanation:** This error repeats the one from line 23, suggesting the same issue remains unresolved.

7. **main.cpp:41:21: error: exponent has no digits**
```cpp
if (it==1.end()) it=1.begin();
