PLEASE HELP ME! Question 1. Mr. Beaver has four friends. They live in different houses. Each day he sets off from
home to visit one friend. When Mr. Beaver reaches a fork in the road he follows the arrow but, as
he passes, turns the arrow so that it now faces in the opposite direction. He always ignores the
arrows when retuming home.
On the first day he visits friend W. On day 2 he visits friend Y because he switched two arrows
around the day before. Etc.

2a) Which friend does Mr. Beaver visit on day 206? Explain your answer.
to come up with your answer

2b) Which aspect(s) of computational thinking were used

1)consider the following code snippet: #ifndef book_h#define book_hconst double max_cost = 1000.0; class book{public: book(); book(double new_cost); void set_cost(double new_cost); double get_cost() const; private: double cost; }; double calculate_terms(book bk); #endifwhich of the following is correct? a)the header file is correct as given.b)the definition of max_cost should be removed since header files should not contain constants.c)the definition of book should be removed since header files should not contain class definitions.d)the body of the calculate_terms function should be added to the header file.

Write a function called checkfactor that takes two arrays of positive numbers, firstnumberrow and secondnumberrow. checkfactor checks if the first entry in firstnumberrow is divisible by the first entry in secondnumberrow, and performs the same operation on the next array elements until all entries have been checked. all the numbers are positive and the number of entries in the arrays are the same. the function should return the identified divisible numbers in two row arrays named firstdivisible and seconddivisible.restrictions: branches or loops should not be used. the code must use the internal mod and logical functions.hint: the mod function should be used to determine if two numbers are divisible. ex: for num1 and num2 if mod(num1,num2) is 0, then the two numbers are divisible.this is matlab
