Aabbcc to a2b2c2. It's one of the robust, feature-rich online compilers for python language, supporting both the versions which are Python 3 and Python 2. Thus the compressed string becomes "a2bc3". Getting started with the OneCompiler's Python editor is easy and fast. Actually don't need to Use HashMap to statistic -- like book first. println("Hello World"); String str = "aabbbcccc"; compare(str); public static void compare(String str) { Map<Character,Integer> stringMap = new HashMap<Character,Integer>(); for(int i = 0 ; i < str. out. g. 7.
