The instance of the list gets passed as a parameter in the HashSet constructor. The Set collection does not preserve the order in which the elements get stored. Another instance of the Set gets instantiated with the s1 instance as a constructor parameter. Now, this intersection reference ...
Step 7 − Enter a while loop with the condition "e.hasMoreElements()" to iterate through the keys in the Hashtable. Step 8 − Within the while loop, retrieve the next key from the Enumeration with the usage of the nextElement() method and assign it to the variable "key". Step ...

erase(): Use this function to get rid of items from the HashSet. find():It is a function that searches the HashSet for a certain element. size():The HashSet’s size() function can be used to determine how many elements are there. ...
items in the collection are unique, an index can be built and organized using the hash value for each element in the collection making the Contains method of a HashSet an O(1) operation (it takes the same amount of time to execute regardless of the number of elements in the coll...
And how to determine all the above subsets. A feasible solution can be determined one by one in a manner similar to divide and conquer. For example, we can: First determine what the first number of a certain seed set is And then determine what the second number is ...
