1. Prompt the user to input a matrix

rows = int(input("Enter the number of rows in the matrix: ")) columns = int(input("Enter the number of columns in the matrix: "))

matrix = []

for i in range(rows):

   row = []
   for j in range(columns):
       element = int(input(f"Enter the element at position ({i}, {j}): "))
       row.append(element)
   matrix.append(row)

1. Calculate the total sum of non-zero elements

total_sum = matrixElementsSum(matrix)

1. Print the total sum

print("The total sum of non-zero elements in the matrix is:", total_sum)' > matrixElementsSum.py && chmod +x matrixElementsSum.py && ./matrixElementsSum.py
