To perform matrix addition, we need to follow these steps:

1. Read the dimensions of the matrices from the input. In this case, the dimensions are given as "2 2".

2. Create two empty matrices with the given dimensions. In this case, we create two 2x2 matrices.

3. Read the elements of the first matrix from the input. In this case, the elements are given as "1 2 3 4".

4. Read the elements of the second matrix from the input. In this case, the elements are given as "1 1 2 1".

5. Perform the addition operation by adding corresponding elements from both matrices. In this case, we add (1+1), (2+1), (3+2), and (4+1).

6. Store the result of the addition in a new matrix.

7. Print the result matrix. In this case, the result is "2 3 4 5".

Here is a sample program in Python that implements the above steps:

```python
# Step 1: Read the dimensions
dimensions = input().split()
rows = int(dimensions[0])
cols = int(dimensions[1])

# Step 2: Create empty matrices
matrix1 = [[0 for _ in range(cols)] for _ in range(rows)]
matrix2 = [[0 for _ in range(cols)] for _ in range(rows)]

# Step 3: Read elements of the first matrix
elements1 = input().split()
for i in range(rows):
for j in range(cols):
matrix1[i][j] = int(elements1[i * cols + j])

# Step 4: Read elements of the second matrix
elements2 = input().split()
for i in range(rows):
for j in range(cols):
matrix2[i][j] = int(elements2[i * cols + j])

# Step 5: Perform matrix addition
result = [[0 for _ in range(cols)] for _ in range(rows)]
for i in range(rows):
for j in range(cols):
result[i][j] = matrix1[i][j] + matrix2[i][j]

# Step 6: Print the result matrix
for i in range(rows):
for j in range(cols):
print(result[i][j], end=" ")
print()
```

When you run this program with the given input, it will produce the desired output:

```
2 3
4 5
```

Note: This is just one way to implement the solution. There may be other ways to achieve the same result.
