Find the Sum of All Elements in a Matrix

You are given a matrix of size R*C containing integers. Write a program to find the sum of all elements present in the matrix.

Note: Make sure to read the input matrix correctly and find the sum of all elements in the matrix as specified in the question.

Boundary Condition(s):
2 <= R, C <= 50
-1000 <= Each integer value in the matrix <= 1000

Input Format:
The first line contains two space-separated integers R and C, representing the number of rows and columns in the matrix.
The next R lines contain C integers each, representing the elements of the matrix.

Output Format:
The program should output a single integer, which is the sum of all elements in the matrix.

Example Input/Output 1:
Input:
3 4
5 10 25 8
12 9 7 6
11 14 18 22

Output:
170

Explanation:
To find the sum of all elements in this matrix, we need to go through each element and add its value to the sum.

Example Input/Output 2:
Input:
4 3
30 40 5
16 28 35
55 90 15
10 25 60

Output:
384

Algorithm:

1. Initialize a variable sum to store the sum of elements and set it to 0.
2. Iterate through each row i from 0 to R-1 and for each row: a. Iterate through each column j from 0 to C-1 and for each column:
3. Add the value of the current element matrix[i][j] to the sum.
4. After the loop completes, the variable sum will hold the sum of all elements in the matrix.
5. Return the value of sum.

Here’s the algorithm expressed in pseudocode:

function findSumOfElements(matrix, R, C):
    sum = 0
    for i from 0 to R-1:
        for j from 0 to C-1:
            sum += matrix[i][j]
    return sum

def find_sum_of_elements(matrix, R, C):
    # Initialize sum to store the sum of elements
    sum = 0

    # Iterate through each row
    for i in range(R):
        # Iterate through each element in the row
        for j in range(C):
            # Add the current element to the sum
            sum += matrix[i][j]

    return sum
