Chapter 30.5, Problem 30.5.4CP
Explanation of Solution
Purpose of given code:
The purpose of given code is to print resultant elements in array variable “m” with “IntStream” class using aggregate functions. It prints all distinct values using “distinct()” method and prints all resultant values of array “m[][]” using “forEach()” method with a character “,”...

Write a generic binary search function in its prototype.
int binarysearch(int target, void *base, int n, int esize, int (*compare)(int *, int *));
This question is in Java. We are required to map over some data and incement by 10.
import.java.util.stream.Collectors;
import.java.util.stream.Stream
public class IncrementTheData implements Assignment {public Object solution(ArrayList<Integer> nums) {
Stream.of(1,2,3,4,5,6)
.map(not sure what would go in here)
.collectors(Collectors.toList())return null;}}
//So this is as far as I got with this question. The instructions are vague but I think I'm on the right track. Am I?
Consider a text file of names, with one name per line, that has been compiled from several different sources. A sample is shown below:Brooke TroutDinah SoarsJed DyeBrooke TroutJed DyePaige TurnerThere are duplicate names in the file. We would like to generate aninvitation list but don’t want to send multiple invitations to the sameperson. Write a program that eliminates the duplicate names by usinga HashSet. Read each name from the file, add it to the HashSet, andthen output all names in the HashSet to generate the invitation listwithout duplicates

- Write a program using C++ that uses a hashing algorithm to create a list of students present in a class. Consider the student numbers as keys, while implementing rotation, fold boundary methods and linear probing (include modulo division if necessary) for an array-based list of length 1000. After creating the list, allow the user to search for the name of a student and report its student number.arrow_forwardImplement a merge() variant that replicates the second half of a[] to aux[] in decreasing order before merging back to a[]. This update allows you to delete the code from the inner loop that tests that each of the halves has been exhausted. Please keep in mind that the resulting sort is not stable.arrow_forwardModify FrequencyCounter to take thename of a dictionary file as its argument, count frequencies of the words from standardinput that are also in that file, and print two tables of the words with their frequencies,one sorted by frequency, the other sorted in the order found in the dictionary file.arrow_forward

Ex: If the words list is: ["hey", "hi", "Mark", "hi", "mark"] the dictionary returned from calling build_dictionary(words) is: {'hey': 1, 'hi': 2, 'Mark': 1, 'mark': 1} Ex: If the words list is: ["zyBooks", "now", "zyBooks", "later", "zyBooks", "forever"] the dictionary returned from calling build_dictionary(words) is: {'zyBooks': 3, 'now': 1, 'later': 1, 'forever': 1} The main code builds the word list from an input string, calls build_dictionary() to build the dictionary, and displays the dictionary sorted by key value.
