Hi Friends Hash Map takes 2byte [in Java] for holding a character
So in Amazon - It takes A - 1 M - 1 Z - 1 O - 1 N - 1 But it's time effective! Yes it takes additional space for intergers, for each key 4 byte for an integer!!! :-( *********** public void checkTheFrequency() { for (int i = 0; i < str.length(); i++) { char key = str.charAt(i); if (checkMap.containsKey(key)!= false) { int value = checkMap.get(key); checkMap.put(key, ++value); } else { checkMap.put(key, 1); } } ***************** Best Regards Kaushik -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
