Solution

Claro, vamos a resolver el problema paso a paso.

  1. Inicializamos la variable sum a 0. int sum = 0;

  2. Definimos una matriz bidimensional matrix con los valores dados. int[,] matrix = new int[,] { {1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 0} };

  3. Iniciamos un bucle for que recorre las filas de la matriz. for (int i = 0; i < matrix.GetLength(0); i++) {

  4. Dentro del bucle, inicializamos la variable product con el primer elemento de la fila actual. int product = matrix[i,0];

  5. Iniciamos un segundo bucle for que recorre las columnas de la fila actual, comenzando desde la segunda columna. for (int j = 1; j < matrix.GetLength(1); j++) {

  6. Multiplicamos product por el elemento actual de la matriz. product *= matrix[i, j];

  7. Sumamos el valor de product a sum. sum += product;

  8. Cerramos ambos bucles y finalmente imprimimos el valor de sum. Console.WriteLine(sum);

Ahora, vamos a calcular el valor de sum paso a paso:

  • Para la primera fila {1, 2, 3}:

    • product = 1
    • product *= 2product = 2
    • sum += 2sum = 2
    • product *= 3product = 6
    • sum += 6sum = 8
  • Para la segunda fila {4, 5, 6}:

    • product = 4
    • product *= 5product = 20
    • sum += 20sum = 28
    • product *= 6product = 120
    • sum += 120sum = 148
  • Para la tercera fila {7, 8, 0}:

    • product = 7
    • product *= 8product = 56
    • sum += 56sum = 204
    • product *= 0product = 0
    • sum += 0sum = 204

Por lo tanto, el valor que se imprime es 204.
