Question
Given two arrays A and B of equal size N, the task is to find a vector containing only those elements which belong to exactly one array - either A or B - but not both. That is, if some element x appears in both A and B it should not be included in the output vector. Complete the implementation of "getVector(vector<ll>A, vector<ll>B, int N)" function.
Example:
Input:
1
3 5 7 1 3
2 4 6 7 8
Output:
3 5 1 3 2 4 6 8
The driver codes are attached in the images below. DO NOT CHANGE THE PROVIDED DRIVER CODES AT ALL, LEAVE THEM EXACTLY THE SAME. ONLY ADD CODE TO THE "getVector(vector<ll>A, vector<ll>B, int N)" FUNCTION
![```cpp
// { Driver Code Starts
// Initial function template for C++
#include<bits/stdc++.h>
using namespace std;
#define ll long long
// } Driver Code Ends
// User function template for C++
class Solution{
public:
// Function to return the output vector.
vector<ll> getVector(vector<ll> A, vector<ll> B, int N) {
// code here
}
};
// { Driver Code Starts.
int main()
{
int t;
cin>>t;
while(t--) {
int n;
cin>>n;
vector<ll> arr(n,0), brr(n,0);
// increase the count of elements in first array
for(ll i=0;i<n;i++)
cin >> arr[i];
```
#### Explanation:
This C++ code sets up the basic structure for solving a problem involving vectors. It includes:
1. **Headers and Macros**:
- Utilizes the `bits/stdc++.h` header for comprehensive library support.
- Defines `ll` as a macro for `long long` to simplify usage.
2. **Solution Class**:
- Contains a public function `getVector` which is currently a placeholder and returns a vector of type `long long`. It takes two vectors and an integer as parameters.
3. **Main Function**:
- Manages multiple test cases (`t` test cases).
- For each test case, reads an integer `n`.
- Initializes two vectors `arr` and `brr` of size `n`, starting with zero values.
- Reads `n` integers into the `arr` vector.
The code doesn't detail the logic within the `getVector` function, indicating that the functional logic needs to be implemented as per specific problem requirements.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F220fce40-52d4-4175-9c12-2aa3a603c4e5%2F9b2d567c-83c7-4c23-85b0-6dda3fd55edc%2F8kw12ce_processed.jpeg&w=3840&q=75)

for(ll i=0; i<n; i++)
cin >> brr[i];
Solution ob;
for(auto x: ob.getVector(arr, brr, n))
cout << x << " ";
cout << endl;
return 0;
} // } Driver Code Ends
```
*Explanation*:
1. **Loop**: The code begins with a `for` loop that reads input values into an array `brr[]`.
2. **Solution Object**: An object `ob` of the class `Solution` is created.
3. **Enhanced Loop**: Another `for` loop iterates over the elements returned by the method `getVector` of the `Solution` class, passing `arr`, `brr`, and `n` as arguments.
4. **Output**: Each element `x` is printed followed by a space.
5. **End of Program**: The program concludes with a return statement for `main`, and the notation `// } Driver Code Ends` indicates the end of the driver code used for execution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F220fce40-52d4-4175-9c12-2aa3a603c4e5%2F9b2d567c-83c7-4c23-85b0-6dda3fd55edc%2Fw7no9c_processed.jpeg&w=3840&q=75)

Follow-up Question
This answer does not assist with the question, I am asking about the at() function. I understand and can complete the for loop.
