1. "Give an example of a function that is defined on the set of integers that is not a one-to-one function."
Keep in mind that the above domain must be the set of integers. Identify what your codomain is, too.

2. "Give an example of a function that is defined on the set of rational numbers that is not an onto function."
The above domain must be the set of rational numbers. Identify what your codomain is, too. This is especially important when explaining why a function is not onto.

3. "Give an example of a function defined on the real numbers that is a one-to-one correspondence."
The above domain must be the set of real numbers. Identify what your codomain is, too.

In Java, a set of integers is given. write a function to find 2 integers in this set that sums upto a target value. i.e [1,5,2,0,11,3] target = 7 result [5,2] i.e [1,5,4,0,14,-7] target = 9 result [5,4] NOTE: THE SAME INTEGER CANNOT BE USED TWICE !!!

The subset-sum problem is defined as follows. Given a set of n positive integers, S = {a1, a2, a3, ..., an} and positive integer W, is there a subset of S whose elements sum to W? Design a dynamic program to solve the problem. (Hint: uses a 2-dimensional Boolean array X, with n rows and W+1 columns, i.e., X[i, j] = 1,1 <= i <= n, 0 <= j <= W, if and only if there is a subset of...

For the following Ackerman function defined for non-negative integers, write a Java program that: Contains a method called computeAckermann that takes two integer values as parameters and calculates and returns the value of the Ackerman function. The method should be defined inside a class named Ackermann. Test the implementation of Ackerman in (a) by calling it from main function and printing the returned value. The main function should be defined in a separate class named AckermannDemo.
