# Sum input numbers
|
|
|
|
Write the function `sumInput()` that:
|
|
|
|
- Asks the user for values using `prompt` and stores the values in the array.
|
|
- Finishes asking when the user enters a non-numeric value, an empty string, or presses "Cancel".
|
|
- Calculates and returns the sum of array items.
|
|
|
|
P.S. A zero `0` is a valid number, please don't stop the input on zero.
