Today’s exercise is a fun little interview question:
You are given a string O that specifies the desired ordering of letters in a target string T. For example, given string O = “eloh” the target string T = “hello” would be re-ordered “elloh” and the target string T = “help” would be re-ordered “pelh” (letters not in the order string are moved to the beginning of the output in some unspecified order).
Your task is to write a program that produces the requested string re-ordering. When you are finished, you are welcome to read or run a suggested solution or to post your own solution or discuss the exercise in the comments below.
