Hashing Create a method hashSetExe to use Java HashSet to store elements and print them. For example, input the elements: “Apple”, “Mango”, and “Grapes”. Please state what the output would be when printing the HashSet with the three elements. Create a method treeSetExe to use Java TreeSet to store elements and print them. For example, input the elements: “Apple”, “Mango”, and “Grapes”. Please state what the output would be when printing the TreeSet with the three elements. Create a hashing function that takes the string, calculate the sum of the ASCII code of each character, and return (sum%tableSize) as the index. For example, hash(“ab”, 11) returns 8, because ‘a’ is 97 and ‘b’ is 98, which adds up to 195, and 195%11 returns 8.
