2022-8: Let's Split!
Write a function that:
- takes a right argument that is a non-empty character vector or scalar.
- takes a left argument that is a non-empty character vector or scalar.
- returns a 2-element vector of character vectors in which the right argument is split immediately before the first occurence of any element in the left argument. If no left-argument element occurs in the right argument, then the split should happen after the last element of the right argument.
Hint: The take X↑Y and drop X↓Y functions, or the partitioned enclose function X⊂Y, could be helpful.
Examples:
'do' (your_function) 'Hello World'
┌────┬───────┐
│Hell│o World│
└────┴───────┘
'KEI' (your_function) ⎕A ⍝ ⎕A is the system constant that contains the characters A-Z
┌────┬──────────────────────┐
│ABCD│EFGHIJKLMNOPQRSTUVWXYZ│
└────┴──────────────────────┘
(⌽⎕A) (your_function) ⎕A
┌┬──────────────────────────┐
││ABCDEFGHIJKLMNOPQRSTUVWXYZ│
└┴──────────────────────────┘
⎕D (your_function) ⎕A ⍝ ⎕D is the system constant that contains the characters 0-9
┌──────────────────────────┬┐
│ABCDEFGHIJKLMNOPQRSTUVWXYZ││
└──────────────────────────┴┘
⎕D (your_function) 'Q'
┌─┬┐
│Q││
└─┴┘
⎕A (your_function) 'Q'
┌┬─┐
││Q│
└┴─┘
