Chapter 19.8, Problem 19.8.2CP
Explanation of Solution
JVM loading things:
- JVM is Java Virtual Machine which is used to load the pre-defined class at runtime.
- If the program uses generic classes “ArrayList<String>” and “ArrayList<Date>”, the classes are not loaded by JVM. The predefined class “ArrayList” only loaded in the JVM at run time...

A robot is initially located at position (0; 0) in a grid [?5; 5] [?5; 5]. The robot can move randomly in any of the directions: up, down, left, right. The robot can only move one step at a time. For each move, print the direction of the move and the current position of the robot. If the robot makes a circle, which means it moves back to the original place, print "Back to the origin!" to the console and stop the program. If it reaches the boundary of the grid, print \Hit the boundary!" to the console and stop the program.
A successful run of your code may look like:Down (0,-1)Down (0,-2)Up (0,-1)Left (-1,-1)Left (-2,-1)Up (-2,0)Left (-3,0)Left (-4,0)Left (-5,0)Hit the boundary!
or
Left (-1,0)Down (-1,-1)Right (0,-1)Up (0,0)Back to the origin!
About: This program is to give you practice using the control ow, the random number generator, and output formatting. You may use <iomanip> to format your output. You may NOT use #include "stdafx.h".
1. In C++, Displaying the elements of array using while loop?
In C++ language
For number 2 through 4 create an integer array with 100 randomly generated values between 0 and 99; pass this array into all subsequent functions. Place code in your main to call all the methods and demonstrate they work correctly.
Using just the at, length, and substr string methods and the + (concatenate) operator, write a function that accepts a string s, a start position p, and a length l, and returns a subset of s with the characters starting at position p for a length of l removed. Don’t forget that strings start at position 0. Thus (“abcdefghijk”, 2, 4) returns “abghijk”
Create a function that accepts the integer array described above returns the standard deviation of the values in a. The standard deviation is a statistical measure of the average distance each value in an array is from the mean. To calculate the standard deviation, you first call a second mean function that you need to write (do not use a built in gadget. Then sum the square of the difference…

- mergeAndRemove(int[], int[]) This is a public static function that takes a int[] and int[] for the parameters and returns an int[]. Given two arrays of integers. Your job is to combine them into a single array and remove any duplicates, finally return the merged array.arrow_forward8. using c++, Write a function method that determines the mean of all the values in an array of integers. Your mean function should call a separate function that you write that determines the sum. Don’t use built-in sum or mean gadgets, but roll your own.arrow_forwardWrite in C++ When you're processing data, it’s useful to break up a text string into pieces using a delimiter. Write a function split() that takes a string, splits it at every occurrence of a delimiter, and then populates an array of strings with the split pieces, up to the provided maximum number of pieces. Function specifications: Name: split() Parameters (Your function should accept these parameters IN THIS ORDER): input_string string: The text string containing data separated by a delimiter separator char: The delimiter marking the location where the string should be split up arr string array: The array that will be used to store the input text string's individual string pieces arr_size int: The number of elements that can be stored in the array Return Value: int: The number of pieces the input text string was split into Note: No input will have delimiters in the beginning or the end of the string.

- 23. Is there any inbuilt function in JAVA that takes two arrays as the parameters and returns true if both the array are equal and returns false otherwise?arrow_forwardWrite a function named minLok (int a, int dimension) that takes the integer array and its size as a parameter and returns the index of the minimum element in the array (where it is in the array). Write an appropriate main method to call this function. In C++.arrow_forward[Fish Tank] You play with a clown fish that has an initial size so. The fish can eat other fish in a tank organized in m columns and n rows. The fish at column i and row j has a positive size si,j. When your fish eats another fish, it grows by that amount. For example, if your clown fish has a size of 10 and eats a fish of size 5, it becomes of size 15. You cannot eat a fish that is bigger than your size. The game starts by eating any fish in the first (left-most) column that is not bigger than yours. After that, you advance one column at a time by moving right. You have only three allowed moves. You either stay at the same row, move one row higher or one row lower. You will always move to the right. Thus, you will make exactly m moves to advance from left to right. Your goal is to exit the fish tank from the right with the biggest possible size. The figure below shows an example with the best answer highlighted. In this case, the final fish size is 71 (10+8+7+24+22). You are required…arrow_forward
- Help with a lisp function (please post photos) A lisp function that generates a random day of the week, then displays a message saying that "Today is ... and tomorrow will be ...". For this purpose, create a global variable before the function containing the days of the week as a list. Then use the built-in function random first to generate a number between 0 and 6 (including). The expression (random) by itself generates a random integer. You can call it with one parameter to return a value within the range from 0 to the value of the parameter-1. For example, (random 10) will return a value between 0 and 9. Next, use the number generated at the previous step to retrieve the symbol for the day of the week from the list. Use the built-in elt function. We want the name of the day to appear capitalized. For this, extract the symbol-name of the day first, then apply the built-in function capitalize to it. Use the result in the princ function call, and do the same thing for the next day.…arrow_forwardThe international standard letter/number mapping for telephones is: Write a function that returns a number, given an uppercase letter, as follows:def getNumber(uppercaseLetter):Write a test program that prompts the user to enter a phone number as a string.

- In C++ The function below, zeroesToFives takes an array of integers and changes any zeroes in the array to fives and returns the count of array elements that were updated. Write at least ten test cases using assertions for zeroesToFives. You should test at least three boundary/edge cases.arrow_forwardin C++ please 1. Write a recursive function called sumover that has one argument n, which is an unsigned integer. The function returns a double value, which is the sum of the reciprocals of the first n positive integers. (The reciprocal of x is the fraction 1/ x .) For example, sumover(1) returns 1.0 (which is 1/1); sumover(2) returns 1.5 (which is 1/1 + 1/2); sumover(3) returns approximately 1.833 (which is 1/1 + 1/2 + 1/3). Define sumover(0) to be zero. Do not use any local vari- ables in your function. Submit output for when n=290 2. isPal funcitonImplement the recursive function isPal(), which determines whether a string str isa simple palindrome. A simple palindrome is a string consisting entirely of thecharacters a-z that reads the same forward and backward. For instance, theupcoming are palindromes: dad, level, mom, madamimadam,gohangasalamiimalasagnahog.Use the following declaration of isPal():bool isPal (const string& str, int startIndex, intendIndex);It returns true…arrow_forwardIn java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…arrow_forward
