- There may be extra spaces or formatting characters at the start or end of a string when interacting with a string object. Spaces and other characters can be taken out of either end of a string using the Trim and TrimEnd methods. You can provide a character or an array of characters to cut. If you give an array of characters, the string will be cut if any of the characters are found in the array.To remove spaces from the start and end of a group of string values, write a C# programme:Using jGRASP please de-bug this /**This program demonstrates an array of String objects.It should print out the days and the number of hours spent at work each day.It should print out the day of the week with the most hours workedIt should print out the average number of hours worked each dayThis is what should display when the program runs as it shouldSunday has 12 hours worked.Monday has 9 hours worked.Tuesday has 8 hours worked.Wednesday has 13 hours worked.Thursday has 6 hours worked.Friday has 4 hours worked.Saturday has 0 hours worked.Highest Day is Wednesday with 13 hours workedAverage hours worked in the week is 7.43 hours*/{public class WorkDays{public static void main(String[] args){String[] days = { "Sunday", "Monday", "Tuesday","Wednesday", "Thursday", "Friday", "Saturday"}; int[] hours = { 12, 9, 8, 13, 6, 4}; int average = 0.0;int highest = 0;String highestDay = " ";int sum = 0; for (int index = 0; index < days.length; index++){System.out.println(days[index] + " has "…Arrays: create an array of a given type and populate its values. Use of for loop to traverse through an array to do the following : to print the elements one by one, to search the array for a given value. ArrayList: create an ArrayList containing elements of a given type . Use some of the common ArrayList methods to manipulate contents of the ArrayList. Write methods that will take an ArrayList as its parameter/argument ; and/or return an ArrayList reference variable as its return type. Searching for an object in an Array: Loop through the ArrayList to extract each object and to check if this object’s attribute has a given value. Explain how and why interfaces are used in Java Collection Framework. Explain the major differences between a Stack and a Queue. Be able to use stack and queue methods. What is meant by O(N) notation? Express the complexity of a given code using the O(N) notation.
- DNA Max Write code to find which of the strands representing DNA in an array String[] strands representing strands of DNA has the most occurrences of the nucleotide represented by parameter nuc. Complete the definition of the class DnaMax and method definition maxStrand shown below. If more than one strand has the same maximal number of the specified nucleotide you should return the longest strand with the maximal number. All DNA strands have different lengths in this problem so the maximal strand will be unique when length is accounted for. Return this uniquely maximal strand. Each String representing a DNA strand will contain only cytosine, guanine, thymine, and adenine, represented by the characters 'c', 'g', 't', and 'a', respectively. If no strand in the array contains the specified nucleotide return the empty string "". public class DnaMax { public String maxStrand(String[] strands, String nuc) { // fill in code here } } Constraints strands will contain no more than 50 elements,…java The search method accepts ArrayList of Strings and String find. The method returns a String. It will look for an element within ArrayList that contains value of find if it finds it, methods needs to return whole Element value. if an instance of find doesn't exist return:"search failed" Example: search(["one apple","two orange","four banana"],"four") returns: "four banana" ("four banana" contains "four" so method returns "four banana")Area code processing In US, long distance phone call is made by dialing the three digits area code first, followed by 7 digits phone number The following is a list of some US area code using JavaScript code (not the most current.

- Project Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverseWords (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat BirdWrite a program in Java programming language that reads an array of strings! The program should write all the strings from array that end with letter 'a'.JAVA PLEASE FAAST Write a java method that receives a string containing letters of the English alphabet and then prints the Letters whose frequencies are not unique. Notes: 1) Ignore letter case; Uppercase and lowercase letters are considered the same. 2) Do not use methods from the Arrays class.
- in c# Write a console app that inputs a sentence from the user (assume no punctuation), then determines and displays ONLY THE DUPLICATE words in alphabetical order. Treat uppercase and lowercase letters the same. [Hint: You can use string method Split with no arguments, as in sentence.Split(), to break a sentence into an array of strings containing the individual words. By default, Split uses spaces as delimiters. Use string method ToLower before calling Split.]Project Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverse Words (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat Bird___5___. You are given an array of strings arr. A string s is formed by the concatenation of a subsequence of arr that has unique characters. Return the maximum possible length of s. A subsequence is an array that can be derived from another array by deleting some or no elements without changing the order of the remaining elements. Example 1: Input: arr = ["un","iq","ue"] Output: 4 Explanation: All the valid concatenations are: - "" - "un" - "iq" - "ue" - "uniq" ("un" + "iq") - "ique" ("iq" + "ue") Maximum length is 4. Question is here to solve------.
