Chapter 1: Problem 3

Write an algorithm that prints out all the subsets of three elements of a set of \(n\) elements. The elements of this set are stored in a list that is the input to the algorithm.

Short Answer

Expert verified
The algorithm involves creating a helper function to generate all subsets of size 3. The Python itertools.combinations() function can be used for this task. After generating the subsets, the algorithm will print them.

Step by step solution

01

Creating a Helper Function

Create a helper function that generates all subsets of a specific size from a given set, for this case, the size is 3. In Python, a handy function for this in the itertools module is combinations(). This function takes two parameters: the list (iterable), and the length of the subsets to be created (r). It returns an iterator that produces all possible subsets of the given length from the provided list.
02

Using the Helper Function

Use the helper function on the provided list of elements to generate all subsets of size three. As the combinations() function outputs an iterator, convert the output into a list so it's easier to work with.
03

Printing the Subsets

Print the subsets. This step could imply iterating through the list of subsets and printing each one, or just printing the entire list, depending on the specific requirements of the exercise.

Write a linear-time algorithm that sorts \(n\) distinct integers ranging from 1 to 500 , inclusive. (Hint: Use a 500 -element array.)

Algorithm 1.7 (nth Fibonacci Term, Iterative) is clearly linear in \(n,\) but is it a linear-time algorithm? In Section 1.3 .1 we defined the input size as the size of the input. In the case of the \(nth\) Fibonacci term, \(n\) is the input, and the number of bits it takes to encode \(n\) could be used as the input size. Using this measure the size of 64 is \(\lg 64=6,\) and the size of 1024 is \(\lg 1024=\) 10\. Show that Algorithm 1.7 is exponential-time in terms of its input size. Show further that any algorithm for computing the \(nth\) Fibonacci term must be an exponential-time algorithm because the size of the output is exponential in the input size. See Section 9.2 for a related discussion of the input size.

Using the definitions of \(O\) and \(\Omega\), show that \\[ 6 n^{2}+20 n \in O\left(n^{3}\right) \quad \text { but } \quad 6 n^{2}+20 n \notin \Omega\left(n^{3}\right) \\]

Justify the correctness of the following statements assuming that \(f(n)\) and \(g(n)\) are asymptotically positive functions. (a) \(f(n)+g(n) \in O(\max (f(n), g(n))\) (b) \(f^{2}(n) \in \Omega(f(n))\) (c) \(f(n)+o(f(n)) \in \Theta(f(n)),\) where \(o(f(n))\) means any function \(g(n) \in\) \(o(f(n))\)

Discuss the reflexive, symmetric, and transitive properties for asymptotic comparisons \((O, \Omega, \theta, o)\)
