In $12.2 Lamport's Hash we mentioned the notion of using only 64 bits of the hash. At each stage, 128 bits are computed, 64 bits are thrown away, and the hash of the retained 64 bits is used in the next stage. The purpose of only using 64 bits is so that a human does not need to type as long a string. Assuming the person will still only type 64 bits, does it work if hash" does a hash of all 128 bits of hash"-1, but what the person actually transmits is 64 bits of the result?

A group of students writes their names and unique student ID numbers on sheets of paper. The sheets are then randomly placed in a stack. Their teacher is looking to see if a specific ID number is included in the stack. Which of the following best describes whether their teacher should use a linear or a binary search? a. The teacher could use either type of search though the binary search is likely to be faster b. The teacher could use either type of search though the linear search is likely to be faster c. Neither type of search will work since the data is numeric d. Only the linear search will work since the data has not been sorted

Calculate the time complexity of the following issue and provide a method. Divide a list of n unique positive numbers into two sublists, each of size n/2, so that the difference in the sums of the integers in the two sublists is as large as possible. You may assume that n is a power of two.
3) WAP in Java to count the number of words in a string using HashMap.
Java's HashMap is implemented as a hash table. The put method stores a value with its associated key. Assuming that the put method takes .001 seconds for a HashMap containing 1,000 values, roughly how long would you expect put to take when called on a HashMap containing 100,000 values? Group of answer choices .001s .01s .1s 1.0s 10.0s

Write a program that receives an integer and displays its first ten multiples in decreasing order. For example, if the integer is 5, he first ten multiples are displayed as 50, 45, 40, 35, 30 25, 20, 15, 10, 5. Use the StackOfIntegers class to store the multiples (e.g., 5, 10, ..., 50) and retrieve and display the multiples in reverse order.
Write a Java program that creates and maintains a binary search tree (BST) whose nodes are student records. Each student record (BST node) contains the student's id (String), name (String) and GPA (float). Use the student id as a key for the BST. The program starts with an empty BST and offers the following menu options to the user repeatedly until the user selects the 'Q' option (quit). A: Add a new student record to the BST. Here the user is prompted to enter the new student’s id, name and GPA. The program should display an error message if the student id already exists in the BST. F: Find a student record. Here the user is prompted to enter the id of the student to be searched. If found the program displays the student id, name and GPA, otherwise the program displays an error message. D: Delete a student record. Here the user is prompted to enter the id of the student record to be deleted. The program should display an error message if the student id is not found in the BST. P:…
