OpenMP C++

With the following code, create 3 versions:

  1. Outer loop parallelism: use a single OpenMP pragma only at the outer loop
  2. Inner loop parallelism: use a single OpenMP pragma only at the inner loop (use reduction)
  3. Nested loop parallelism: use pragmas at both the outer loop and inner loop

-----

#pragma omp parallel for 
   for(int i = 0; i < n; i++)
   {
    #pragma omp parallel for    
        for(int j = 0; j < n; j++)
        {
                y[i] += A[i * n + j] * x[j];
        }
