Explanation of Solution
Given
//Initialize the variable
double input = 0;
//Check the value is double
while (in.hasNextDouble())
{
//Initialize the variable previous
double previous = input;
//Get the input from the user
input = in.nextDouble();
//Check whether the input equals to previous

Explanation of Solution
Solutions to overcome the problem:
One solution to overcome the above mentioned problem is to introduce a Boolean variable. It checks whether the loop is entered for the first time.
Algorithm after introducing the Boolean variable:
//Initialize the variable
double input = 0;
boolean first = true;
//Check the value is double
while (in.hasNextDouble())
{
//Initialize the variable previous
double previous = input;
//Get the input from the user
input = in.nextDouble();
if (first)
{
//Assign false to the variable first

- We often used slicing of arrays as examples when we were learning recursion. These are excellent examples for learners, but in the real world they have a significant problem. What is the problem? Enter your answer here Explain an easy trick that we can use to get around this problem, while still retaining the recursive nature of our solution. Enter your answer herearrow_forwardThere is an N of components, represented by the strings S1,S2, .... SN into the kitchen. The chef took all the ingredients, put them in a cauldron and mixed them. In the cauldron, the letters of the strings representing the ingredients are completely shuffled, so that each letter appears in the cauldron as many times as it has appeared in all the strings combined; now the cook can take out one letter from the cauldron at will (if that letter appears in the cauldron more than once, it can be taken out that many times) and use it in a dish. Complete Food is a "chef" chain. Help the chef find the maximum number of complete meals he can make! Please Answer in Java Programming language.

Analyze your algorithm, and give the results under order notation.arrow_forward

In this case, "diagonal" means all diagonals, not just the two that bisect the board.arrow_forwardApply algorithm 4.3.2 in P.155 with n=6 and A=(3,5,4,1,3,2). Draw only the right half of the corresponding walkthrough as shown in P.155, showing only the list A at the end of the outer “for” loop.arrow_forward
- Implement a recursive procedure in UCBLogo, which will draw a set of circles arranged in a circle. It must be possible to specify the number of circles that have to be drawn in a simple fashion (i.e. with minor modification to the program source code).arrow_forwardThe example on page 190 of the textbook shows the restoring division of dividing 7 by 2. Redo the same example by now dividing 15 by 2. Confirm that the quotient is 7 and the remainder is 1 at the end of the algorithm's execution.

You have to take that number n from the user.arrow_forwardFor your initial post, identify a single algorithm that you use in your day to day life which involves repetition. As an example, washing each dish in a stack of dishes or a walk/don't walk sign switching from one mode to another after a set amount of time. Detail the steps of your algorithm in your post. As you detail the steps, make sure you break down each step fully. At a high level, explain how you would go about implementing the loop. Would you implement a while loop? A for loop? Would you make use of a "break statement?" Would your solution involve a nested loop?arrow_forwardDevelop Pseudo-code (English-like) for: In the Find Largest pseudo-code algorithm of Figure 2.14, listed below, if the numbers in our list were not unique and therefore the largest number could occur more than once.
