Identify the following sorting
Step by step
Solved in 2 steps with 1 images
- java: Run length coding is a method to represent a string in a more compact manner. Each character that occurs more than 2 times in a row is represented by the character and a number following it. Two examples are: "abba" → "abba""abcccbbbba" → "abc3b4a"Write a function that calculates how many characters the encoded string is shorter than the original.In java 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, 1, 4, 6}, the function would return 6, since the subsequence {1, 4, 6} is the longest that is strictly increasing. Develop a function that takes a string…Write a Java program: A palindromic number or palindrome number is a number that remains the same when its digits are reversed. Like 16461. Write a Java program that implements the helper method isPalindrome() that decides whether a given int number is a palindrome or not. Do not use ready String class functions like reverse() or arrays and array functions!!! Input FormatA line contains an Integer N. Constraints 1 <= N <= 999999 Output FormatA text containing either "This number is a palindrome" or "This number is not a palindrome" (the code should have the structure as in the picture)
- Public class Utilities { getDigits Method: public static java.lang.String getDigits(java.lang.String str) Returns a string with the digits (if any) present in the str parameter. You can assume str will never be null. You can use Character.isDigit() to determine whether a character is a digit. You may not use an auxiliary method in order to implement this method. Your implementation must be recursive and you may not use any loop construct. From the String class, the only methods you can use are length(), isEmpty(), charAt() and substring. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: str - Returns: String with digits or empty stringJava Without using any java functions, data structures, libraries, string builder or anything complicated. Please make a program that takes out the tokens in a string. For example "90+5" -> 90 + 5 Make It so it is null if string is empty " " --> null Make it so it is null if expression is invalid "++7 - 0" --> null and "..7 + 0" --> null Use this for loop to iterate through the list for (int i = 0; i < exprn.length(); i++) {Java programming please type the code CountOccurrences(String[], String) This is a public static function that takes a String[] and a string for the parameters and returns an int. This function should count the number of times a given pattern (the second parameter) is found within each string in an array of strings (first parameter). Then the function should return the total number of occurrences. Arguments: String[] array - An array containing at least one string String pattern - A string containing at least one character. returns int - The number of times the pattern is found in the strings in the array. Example: array = ["aba", "ckel", "kealska"] pattern = "a" output = 4
- 1. Given a string of at least 3 characters as input, if the length of the string is odd return the character in the middle as a string. If the string is even return the two characters at the midpoint. public class Class1 { public static String midString(String str) { //Enter code here } } ----------- 2. Given an array of integers return the sum of the values stored in the first and last index of the array. The array will have at least 2 elements in it public class Class1 { public static int endSum(int[] values) { //Enter code here } } ----------- 3. The method takes a string as a parameter. The method prints treat if the string is candy or chocolate (of any case, such as CaNdY) Otherwise print trick import java.util.Scanner; public class Class1 { public static void trickOrTreat(String str) { //Enter code here } public static void main(String[] args) { Scanner s = new Scanner(System.in); trickOrTreat(s.nextLine()); } }Class Utilities { Method Details addDelimiter: public static java.lang.String addDelimiter(java.lang.String str, char delimeter) Returns a string where characters are separated by the specified delimeter character. A string with a single character will not have a delimeter added. The space character is consider a character (similar to character 'A'). You can assume str will never be the empty string. You may not use an auxiliary method in order to implement this method. Your implementation must be recursive and you may not use any loop construct. Note: In java given two characters a and b, a + b will not create a string. To create a string, append a to the empty string and the result to b. From the String class, the only methods you can use are length(), isEmpty(), charAt() and substring. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: str - delimeter - Returns: String with characters…Code: public class RURottenTomatoes { public static void main (String[] args) { int r = Integer.parseInt(args[0]); int c = Integer.parseInt(args[1]); for ( int i = 0; i < args.length; i++ ) { int[][] array = new int[r][c]; } String input = args[0]; int n = input.length(); String temp; int arrayR = r; int arrayC = c; for ( int i = 0; i < r; i++ ) { temp = input.substring( i, i + 1 ); arrayR = arrayR + Integer.parseInt(temp); for ( i = 0; i < c; c++ ) { temp = input.substring( i + 1, i + 2 ); arrayC = arrayC + Integer.parseInt(temp); } } } } I did all this, but then stuck. I have no idea what to do next, and I think my code is wrong. Can you help me out doing this assignment? Please explain everything that you do clearly! The instructions are below: RU Rotten Tomatoes. Write program RURottenTomatoes.java that creates a 2 dimensional integer array of movie ratings from the command line arguments and displays the index of the movie that has the highest sum of ratings.…
- In java: Develop a function that accepts an array of integers and returns their average. Develop a function that accepts an array of integers and a threshold value from the user. The function returns how many values in the array are strictly greater than the cutoff. Using the functions written for #1, #3, and #4, find the number of values above average in two randomly generated arrays. Develop two functions:a. a function that returns the index of the maximum value in an array of integers passed by a caller, the caller prints the returned index and the value at that indexb. a function that returns the index of the alphabetically first value in an array of strings, the caller prints the returned index and the value at that inde Develop two functions:a. a function that swaps the alphabetically first value in an array of Strings with the first value in the array. Call this function twice on two different arrays of Strings; in the caller, use the function written for #2b to display…5.17 LAB: Word frequencies (JAVA) Write a program in java that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain fewer than 20 words. Ex: If the input is: 5 hey hi Mark hi mark the output is: hey - 1 hi - 2 Mark - 1 hi - 2 mark - 1 Hint: Use two arrays, one array for the strings and one array for the frequencies.java getDup accepts an array and returns an int. If there is any element is duplicated, the method counts how many of those present in the array. Example : getDup(["1","2","aa"',"1"]) returns:2 ("1" is duplicated and there are two "1"s so return is 2) class Main { public static int getDup(String[] r) { } public static void main(String[] args) { Scanner in = new Scanner(System.in); String [] strs = new String[in.nextInt()]; for(int i=0; i < strs.length; i++) { strs[i] = in.next(); } System.out.println(getDup(strs)); } } hint: you will need a nested array the will run on the array we get from the method argument. inside the nested loop you will need to check if the main array element is equal to the current
