For Listing 5.8, another solution to find the greatest common divisor of two integers n1 and n2 is as follows: First find d to be the minimum of n1 and n2, and then check whether d, d - 1, d - 2, ..., 2, or 1 is a divisor for both n1 and n2 in this order. The first such common divisor is the greatest common divisor for n1 and n2.

0. Good binary strings are strings made of Os and 1s where there are no two consecutive Os. For example, 1011011101, 011010 etc. How many good binary strings of length k are there? [Hint: First you may try to find the highest possible number of Os in such strings in terms of k . It can be done separately for odd and even k. Use the Floor function to generalize. Giving the final answer in summation (E) form will suffice.]

In-Class Assignment Consider an (8,4) binary linear block code with minimum distance of 4. • How many valid codewords are there? • What is the code rate? • What is the minimum weight of the code? • If the code is used for error detection only, how many errors can it detect? • If the code is used for error correction, how many errors can it correct?
Using Lisp, implement a program that solves the Missionaries and Cannibals problem that uses a DFS( depth first search). The function call should use (mac start(this is the current state of the problem) end(this is the desired state)). So the problem should output sequences of moves to go from the start state to the desired state! For example, the call should be like: Call: (mac '(3 3 l) '(0 0 r)) Output: ((3 3 L) (2 2 R) (3 2 L) (3 0 R) (3 1 L) (1 1 R) (2 2 L) (0 2 R) (0 3 L) (0 1 R) (1 1 L) (0 0 R))
The correct statements are: A set is countable iff it is either finite or countably infinite. The set of natural numbers is countable. The power set of the set of natural numbers is countable. For any Σ Ø, Σ* is countably infinite.

Let A be the set of all strings of decimal digits of length 5. For example 24157 and05189 are strings in A.(a) How many strings in A have exactly one 7?(b) How many strings in A have at least two 2’s?(c) How many strings in A have the digits in a strictly decreasing order? For example97643 and 54321 are such strings, but 14820 and 95421 are not.
Give a loop invariant that accurately relates the present values of, r, s, x, and y.Look at the GCD loop property for a hint. This invariant is also true when the calculation is between the first and second step of each iteration, in addition to being true each time the computation is at the top of the loop. Prove that your method creates and keeps the loop invariant as claimed.
Correct answer will be upvoted else downvoted. Computer science. We should characterize the expense of a string s as the number of file sets I and j (1≤i<j<|s|) with the end goal that si=sj and si+1=sj+1. You are given two positive integers n and k. Among all strings with length n that contain just the principal k characters of the Latin letters in order, find a string with least conceivable expense. In case there are different such strings with least expense — see as any of them. Input The main line contains two integers n and k (1≤n≤2⋅105;1≤k≤26). Output Print the string s to such an extent that it comprises of n characters, every its character is one of the k first Latin letters, and it has the base conceivable expense among this load of strings. In case there are various such strings — print any of them
Note: For all integers k,n it is true that kn, k+n, and k-n are integers. An integer k is even if and only if there exists an integer r such that k=2r. An integer k is odd if and only if there exists an integer r such that k=2r+1. For every integer k it is true that if k is even then k is not odd. For every integer k it is true that if k is odd then k is not even. For every integer k it is true that if k is not even then k is odd. For every integer k it is true that if k is not odd then k is even. If P then Q means the same thing as P → Q (P implies Q). 3. Consider the argument form pvr .. p→r Is this argument form valid? Prove that your answer is correct. 4. Prove that for every integer d, if d³ is odd then d is odd.
