Running Sum of Numbers
In this example, we calculate the sum of all ten digits and enable the option "Print Running Sum". We get the intermediate values of the sum in the process of addition. Thus, we have the following sequence in the output: 0, 1 (0 + 1), 3 (0 + 1 + 2), 6 (0 + 1 + 2 + 3), 10 (0 + 1 + 2 + 3 + 4), and so on.
