How can predictive and prescriptive modeling be used to measure operational performance in real-time? Do you see any potential downsides to this application? Can you provide an example?
Tracing the Recursion.
Tracing the Recursion. Observe the recursive solution provided below.
1. Which line(s) of this program define(s) the base case of sumOfDigits() method?
2. Which line(s) of this program include recursive call(s)?
3. Trace the recursion below. You must show the trace step by step; otherwise – little
to no credit!
4. Show me the final result!
