Find duplicate characters and count them from a string by using hash map and without hash map.

Hello there, your way of explaining code is good, however I don't understand that why there was need of initializing count as 0 in hashmap at the end of the code.

what is the point of using hashmap if you are using nested loop in it.

you should put time lapse for with hashmap and without

anyway thanks
