To achieve this, you need to understand .
The final array will have its last column values updated to reflect the array's row length, total element count, and specific mathematical sums as defined by the exercise instructions.
But the problem 8.1.5 usually wants the output to look like a proper grid:
public static void main(String[] args) // Example call printNumbers(5, 10); 8.1.5 Codehs Answers
Always check the language displayed at the top of the exercise.
console.log(sumArray([1, 2, 3, 4])); // Output: 10 console.log(sumArray([-5, 10, 15])); // Output: 20
Remember that the last index of any array is length - 1 . Trying to access array[row][array[row].length] will cause an error. To achieve this, you need to understand
: Create a method that takes the 2D array, the target row, the target column, and the new value as parameters. updateValue( value) arr[row][col] = value; Use code with caution. Copied to clipboard Calculate dynamic values
Possible reasons:
– 8.1.5: sumArray
In this challenge, you are typically provided with a 2D array called array that contains three nested arrays. Each of these sub-arrays has an incorrect value (specifically 0 ) as its last element. Your goal is to:
For students in the course, 8.1.5 is often about Functions with Parameters .
