Given a string,determine if it is compressed of all unique characters. For example, the string ‘abcde’ has all unique characters and should return True.
Given a string in the form ‘AAAABBBBCCCCCDDEEEE’ compress it to become ‘A4B4C5D2E4’. For this problem, you can falsely “compress” strings of single or double letters.
