Problem Statement

Create a function that strips a set of characters from a string.

The function should take two arguments:

The returned string should contain the first string, stripped of any characters in the second argument:

Let's start with the solution:

(defun stripchars (s chars)
  (seq-into
   (seq-filter (lambda (x) (not (seq-contains chars x))) s)
   'string))

(stripchars "She was a soul stripper. She took my heart!" "aei")
