I’ve included an attachment of the instructions. Basically, I already did part 1 A, however, I can’t figure out how to do part 1 B without using loops, recursion and only using higher-order functions in python. For part 1B you need to use the data you’d get from 1A but the only solution I could figure out for 1A uses loops and thus would violate the rules for 1B.
Again in python please do 1B WITHOUT loops, recursion, or list comprehension and only using higher-order functions.
