- The Fibonacci function f is usually defined as follows. f (0) = 0; f(1) = 1; for every n e N>1, f (n) = f(n – 1) + f(n – 2). Here we need to give both the values f(0) and f(1) in the first part of the definition, and for each larger n, f(n) is defined using both f(n - 1) and f(n- 2). Use induction to show that for every neN, f(n) 1; checking the case n = 1 separately is comparable to performing a second basis step.)arrow_forwardYou are given a collection of n bolts of different widths and n corresponding nuts. You are allowed to try a nut and bolt together, from which you can determine whether the nut is larger than the bolt, smaller than the bolt, or matches the bolt exactly. However, there is no way to compare two nuts together or two bolts together. The problem is to match each bolt to each nut. Design an algorithm for this problem with Θ(n log n) average-case complexity (in terms of nut-bolt comparisons). Explain why your algorithm has Θ(n log n) average case complexity.arrow_forwardGiven an integer say 45, to find the sum of 45 with 8 in binary form (see the figure below), we can use the TM designed in slides 79-90 of the notes "Turing Machines and Equivalent Models I" twice to find the result.

Such a TM can be designed by extending the TM designed in slides 79-90 of the notes "Turing Machines and Equivalent Models I". The TM has 14 instructions and 6 states: 0, 1, 2, 3, 4, and halt. Six instructions of such a TM have been given in the first and the second tables below. Fill out the remaining blanks in the first and the second tables and also blanks in the third table to show the remaining instructions of the TM (you have to use your own text boxes here)arrow_forward
