PLEASE RETURN THE ENTIRE CODE, INCLUDING WHAT IS GIVEN (PYTHON) A simple software system for a library models a library as a collection of books and patrons, as per the requirements below: - A patron can have at most three books out on loan at any given time. - Each book has a title, an author, a patron to whom it has been checked out, and a list of patrons waiting for that book to be returned. - When a patron wants to borrow a book, that patron is automatically added to the book’s wait list if the book is already checked out. - When a patron returns a book, it is automatically loaned to the first patron on its wait list who can check out a book. - Each patron has a name and the number of books that patron has currently checked out. Develop the classes Book and Patron to model these objects. Think first of the interface or set of methods to be used with each class, and then choose appropriate data structures for the state of the objects. Here is the code so far, please write the rest…
What would be a way in implementing the Josephus problem in C++ using a vector or a list? That takes in three parameters, one the number of knights for the knight parameter. The second parameter, "skip", is the number of knights to skip and to execute the next night. Then the third parameter "start", is the index of the knight to execute first.
The below code is written in C++, can you please write it in Scheme language with comments or explination? thank you!! void antiSymmetric(int b[], int sizeOfB) { bool hold = true; // set hold to true for(int i = 0; i < sizeOfB;) // for each pair (e,f) in b { if(hold == false) { cout << "AntiSymmetric - No" << endl; break; //Did not find (e,e) in b } for(int j = 0; j < sizeOfB;) { if(b[i] == b[j+1] && b[i+1] == b[j]) //If true, then pair(f,e) exists { if(b[i+1] != b[i]) //If true, relation is antisymmetric { hold = true; break; } else { hold = false; j = j + 2; } } else { hold = false; j = j + 2; } } i = i + 2;
Implement function rotate that takes a string argument s and an integer argument n, and rotates the string s to the left by n times. For example, the code char s[] = "systems"; rotate(s, 3); will change s into "temssys", while the code char t[] = "abcd"; rotate(t, 1); will change t into "bcda". Restrictions: printf and strlen are the ONLY C library functions that you can use in the implementation. void rotate(char *w, int j)

You are given a string of characters. Complete the below recursive method in JAVA or inPython to print the lowercase characters in a reverse manner and also print the count. Scontains the string, i is the starting index and c is the count, which are both initialized to0. [Note for Python Implementation: You are not allowed to use any built-in functionsexcept len(), print(), ord() and chr()]. def printReverse (s, i, c) : #To Do OR public void printReverse (String s, int i, int c) { // To Do } Sample Input Sample Output s = Axy3*8Gw57&Xyu1 count is 4, uwyx
Please implement in Java implement a keyed bag in which the items to be stored are strings (perhaps people’s names) and the keys are numbers (perhaps Social Security or other identification numbers). So, the in- sertion method has this specification: public void insert(String entry, int key);// Precondition: size( ) < CAPACITY, and the // bag does not yet contain any item// with the given key.// Postcondition: A new copy of entry has// been added to the bag, with the given key. When the programmer wants to remove or retrieve an item from a keyed bag, the key of the item must be specified rather than the item itself. The keyed bag should also have a boolean method that can be used to determine whether the bag has an item with a specified key. In a keyed bag, the pro- grammer using the class specifies a particular key when an item is inserted. Here’s an implementation idea: A keyed bag can have two private arrays, one that holds the string data and one that holds the corresponding…
The goal is to rewrite the function, below, such that passes in a different list of parameters, particularly eliminating the need to pass low and high for each recursive call to binary_search. defbinary_search(nums,low,high,item): mid=(low+high)//2iflow>high:returnFalse #The item doesn't exist in the list!elifnums[mid]==item:returnTrue# The item exists in the list!elifitem<nums[mid]:returnbinary_search(nums,low,mid-1,item)else:returnbinary_search(nums,mid+1,high,item) The new function should be prototyped below. The number of changes between the given version, and the one requested is not significant. defbinary_search(nums,item):pass# Remove this and fill in with your code Tip: If you consider that high and low are used to create a smaller version of our problem to be processed recursively, the version requested will do the same thing, just through a different, more Pythonic technique.
Please do this in JAVA PROGRAMMING. Given: List L of pairs of charactersString SOutput: TRUE if S is a valid string, FALSE otherwise. A string is considered valid if each character in the string can be paired with another character in the string, where the pair belongs to the input list L. Furthermore, two pairs cannot cross each other. In other words, a pair most completely enclose another, or be completely separate. Design and implement an efficient dynamic programming solution to this problem. Examples: Input L: (a b) (b c) (c d) (a a) Input S: aaba Output: True (pairs shown color-coded: aaba, "aa" fully encloses "ab") Input L: (a b) (b c) (c d) (a a) Input S: abcaad Output: True (pairs shown color-coded: abcaad, "ab" is separate from the other pairs) Input L: (a b) (b c) (c d) (a a) Input S: acbd Output: False (acbd is not valid because the pairs cross each other.) Input L: (a b) (b c) (c d) (a a) Input S: aaac Output: False
‘Write a function nesting(), which takes an arbitrary number of parameters, and returns a list containing the arguments. Write another function unnesting(), which takes a list L as the parameter and retums a 1D list. Notice that, you should be able to use loops to solve thisproblem and should not use recursive functions (which we will not cover in this course). ‘Write assertions to test the two functions.For example nesting(1, nesting(2, 3, nesting(4, 5, [6])), [7, 8], 9)unnesting([1, [2, 3, [4, 5, [6]]], [7. 8], 9]) (1, [2, 3, [4, 5, [6]]], [7, 8], 9][1, 2,3, 4, 5, 6, 7, 8 9]
Please write a C ++ program that uses “class” to calculate ”Sets“. for example , calculate the union of two sets A and B ,or Cartesian product of two sets A and B ， or the intersection of A and B.
Profile the performance of the memoized version of the Fibonacci function defined in Project 6. The function should count the number of recursive calls. State its computational complexity using big-O notation, and justify your answer. The fib function header has been modified to include the counter as the second parameter. Define the Counter class, it should have three methods: __init__, increment, and __str__. When an instance of the Counter class is passed as a parameter, the count property of that instance should be incremented based on the number of recursive calls. The __str__ method should return the count property's value as a string. ----------------------------------------------------------------------------------- """ File: fib.py Project 11.7 Employs memoization to improve the efficiency of recursive Fibonacci.
