Concept explainers

Declaring and Defining the function

A set of statements, which performs a particular task is called a function. The program gains modularity by using function. The application is quite easy to understand, read, and edit when they are created with functions. The developer/programmer creates a function and uses main() to call the function. Once the function gets executed, the control is transferred to the main program.

Keep in mind that removing a chicken might show a previously hidden chicken. You may find substring and indexOf useful. achickchickenen - removing the 1st chicken would leave achicken behindachicken - removing the 2nd chicken would leave a behindSample Data : itatfunitatchickenfunchchickchickenenickenchickchickfunchickenbouncetheballchickenSample Output : 01302
Problem Description: Implement the described Mancala variant in C++ in the pictures. Player 1 will be a human while the other will be a computer player. The computer player selects a hole following the following decision logic: If there is a hole with enough pieces to finish the turn in the computer player's end zone, select it. Otherwise select the hole on the right to left path with the greatest amount of marbles. If there are no marbles on that path then select the hole closest to the opponent's end zone. It is highly suggested, but not required, to pause the output after the computer makes a move to allow the user to interpret the output before more gets printed out. Look into cin.get(); The program should not allow the player to enter incorrect selections. The player cannot select a nonexistent hole, the end zones, or an empty hole. Look at the example output for an example for how to output the game board formatted in a nice way. You must tell the player what input is valid. For…
Recursion Practice Welcome back! In this lab, we will be reviewing recursion by practicing with some basic recursion problems. Objectives Increase familiarity with recursive logic by working through several recursive problems. Taking into consideration a few corner cases through analyzing the test cases. Using a regex expression that will remove punctuation. Getting Started This lab includes the following .java file: L4/└── Recursion.java└── Main.java**Main.java is a read-only file used for testing. It is not included in the starter jar.Here is the starter jar if you would like to code in a different environment: L4.jar. Please complete ALL functions. Make sure to read the description for each function carefully. Do not include any for or while loops in your methods. These can all be completed in a purely recursive style, so do it recursively! In the spirit of incremental development, implement each method one at a time, look at the test cases and take into consideration what is…
* Assignment: Longest increasing subsequence * * Sequences are a natural source of computational problems. One such * family of problems involves finding subsequences with specified * properties in a given sequence. This exercise asks you to write * a program that, given a sequence * * s(0), s(1), ..., s(n-1) * * of integers as input, finds a ___longest increasing subsequence___ * of the sequence s. * * For example, suppose we are given as input the sequence * * 72, 16, 51, 17, 6, 21, 92, 59, 54, 78, 41, 33, 94, * 85, 83, 56, 2, 46, 57, 44, 73, 6, 47, 47, 0. * * In this sequence, a longest increasing subsequence has length 7. * One example of such an increasing subsequence is * * 16 < 17 < 21 < 54 < 56 < 57 < 73. * * More generally, your program must be such that * given a sequence * * s(0), s(1), ..., s(n-1) * * of integers as input, the program returns a subsequence * * s(i_1), s(i_2), ..., s(i_k) * * that meets all…
// The language is java Part I: Use of recursive method (4 points for students who need recursion/extracredit) Description: Code a class called RecursiveMultiply in which it will accept two integer arguments entered from user; pass these integers to a recursive method that returns the multiplication result of these two integers. The multiplication can be performed as repeated addition, for example, if two integers are 7 and 4: 8 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 You will write the application with GUI and recursion to display the result in a noneditable text field, based on the user’s entry from two text fields, while an OK button is pressed. You will utilize the exception handling code as you did in your Lab 4 and Lab 5 to verify if data entered in the text fields are valid (numerical and positive data only). You will make your own decision if there is any explanation that is not described in this specification. Finally, code a driver program that will test your class…
Topical Information Use C++. This lab will help you practice with dynamic memory (NOT mixed with classes). Program Information Heat flow through a rod can be simulated fairly easily in a computer program. We can simulate the rod using an array of temperatures. The rod begins all at the same temperature (user determined), but holding some position(s) of the rod at constant temperature (holding a match or ice cube to the rod) provides a [set of] heat source(s) (or sink(s)). To update the temperature at each time step (second?), you take the average of the positions on each side from the previous time step (and at the current position). For instance, if the following was the initial state of the rod: +------+------+------+------+------+------+------+------+ | 10 | 10 | 10 | 10 | 10 | 10 | 10 | 10 | +------+------+------+------+------+------+------+------+ And then the user specifies that there is a heat source at the left end of 100 degrees:…
