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
