You are given a binary string str. In a single operation, you can choose two indices L and R such that 1 ≤L≤R≤N and complement the characters between L and Ri.e strL, strL+1,, strp. By complement, w mean change character 0 to 1 and vice-versa. You task is to perform ATMOST one operation such that in final string number of 1s is maximised. If there is no need to completement, i.e., string contains all 1s, return -1. Else, return the two values denoting L and R. If there are multiple solutions, return the lexicographically smallest pair of L and R.

You are given a binary string str. In a single operation, you can choose
two indices Land R such that 1 ≤L≤R≤N and complement the
characters between L and R i.e strL, strL+1,, strp. By complement, we
mean change character 0 to 1 and vice-versa.
You task is to perform ATMOST one operation such that in final string
number of 1s is maximised. If there is no need to completement, i.e.,
string contains all 1s, return -1. Else, return the two values denoting L
and R. If there are multiple solutions, return the lexicographically
smallest pair of L and R.

Write a class called Book having the following data members: title (String), author1 (String), author2(String), publisher (String), yearPublication (int), isbn (String), accessionNum (long), issuedTo (LibMember). Include following public methods in the class: Default constructor (without any parameters), constructor with 6 parameters (except for issuedTo – initialize issuedTo to null), set and get methods for all attributes, equals and toString. NOTE: The ISBN is a unique 13 digit number assigned by the publisher. It is like barcode. As there can be multiple copies of a book in a library, the libraries assign a unique number, called accession number, to every book in the library to keep track of the books in the library. Assume that accession number starts from 1001.
For Java Write code for an if-else block that checks separates integers into the following categories: An integer less than 0, An integer greater than 0 and less than or equal to 10, An integer greater than 10 that is even, and an integer greater than 10 that is odd. Have each category print out a different statement. What are some ways you can make your code more efficient when using if-else blocks?

Understanding ifStatements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is made of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge). A variable for the number of characters initialized to 8 (numChars). A variable for the color of the characters initialized to "gold" (color). A variable for the…
For the code in java below it shows a deck of 52 cards and asks the name of the two players and makes both players draw five cards from the deck. What I want to be added onto the code is the possibility for Player A too chose whatever card they want from his/her 5 cards and Player B has to chose two cards from his/her 5 cards that equal in value of Player A's card. I also want the cards that have been used to be replaced by different cards in the deck of 52 cards and that game to go on until the deck runs out of cards. Main class code: import java.util.ArrayList; import java.util.Scanner; import java.util.List; import java.util.Random; class Main { publicstaticvoid main(String[] args) { // card game, two players, take turns.
