A multidimensional integer array is initialized in the code editor. Print the elements by row starting from the first row going down to the last row.

Sure, here is a step-by-step guide on how to print the elements of a multidimensional array by row:

1. First, you need to identify the array. Let's assume it's named multiArray.

2. Next, you need to create a loop that will go through each row of the array. In most programming languages, this is done with a for loop. The loop should start at 0 (since array indices usually start at 0) and go up to the length of the array. In Java, for example, this would look like:

for (int i = 0; i < multiArray.length; i++) {
    // code to print each row goes here
}

3. Inside this loop, you need to create another loop that will go through each element in the current row. This loop will look very similar to the first one, but it will go up to the length of the current row, like this:

for (int j = 0; j < multiArray[i].length; j++) {
    // code to print each element goes here
}

4. Finally, inside the second loop, you can print each element. In Java, you can use System.out.print or System.out.println to do this. Here's what the final code might look like:

for (int i = 0; i < multiArray.length; i++) {
    for (int j = 0; j < multiArray[i].length; j++) {
        System.out.print(multiArray[i][j] + " ");
    }
    System.out.println(); // print a new line after each row
}

This code will print each element in each row of the array, with a space between each element and a new line after each row.
