Background
Previously, we have built Sum_Scan_Assignment sum_scan. This is a specific version of scan where the operation is +. We will build a higher-order function scan which takes an operation to apply, as well as a list.
Code To Implement
scan
Clients
scan op+
For example:
scan op+ [131,231,425]
would produce:
[131, 362, 787]
xs 131 231 425 scan op+ xs 131 362 787
scan op*
For example:
scan op* [131,231,425]
would produce:
[131, 30261, 12860925]
xs 131 231 425 scan op* xs 131 30261 12860925
