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.

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...

Suppose that two integers from the set of 8 integers {1, 2, … , 8} are choosen at random. Find the probability that 5 and 8 are picked. Both numbers match. Sum of the two numbers picked is less than 4. [3+3+4 marks] Suppose that you pick a bit string from the set of all bit strings of length ten. Find the probability that: The bit string has the sum of its digits equal to seven. The bit string has...
