C++ coding plase
Given three integer numbers N1, N2 and N3. Write 2 overloadedfunctions which perform addition of passed values.
Write two functions inside 'ProblemSolution' class:
Function 1:
solution that accepts two parameters, N1 andN2. A function should return addition of those numbers.
Function 2:
solution that accepts three parameters, N1, N2and N3. A function should return addition of 3 numbers.
Input
    2
    3
    4
Output
    5
    9
Where,
The first line of output contains addition of N1 and N2.
The second line of output contains addition of N1, N2 andN3.
using this code in the problem
#include
using namespace Std;
Class ProblemSolution
{
// write your code here
}:
int main()
{
int N1,N2,N3;
cin >> n1;
cin >> N2;
cin >> N3;
problemSolution problemSolution;
cout << problemSolution.solution(N!,N2)<<\"\n\" ;
cout << problemSolution.solution( N1,N2,N3);
return 0;
