Integers begin$\_$data and end$\_$data are read from input, representing the first and last values of an increasing sequence of integers. Integers sum$\_$vals and data$\_$count are initialized with $0.$ For each integer between begin$\_$data and end$\_$data, both inclusive:

Increase sum$\_$vals by the integer.

Increment data$\_$count.

Output 'Adding: $\text{'}$ followed by each integer's value.
