Step by step
Solved in 2 steps
- 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.java Use Map data structure Write a method that returns the frequency of each characters of a given String parameters If the given String is null ,then return null5.17 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.
- private static String extractVowelHelper(String str, int start, String vowels) { // base case // recursive step }Java 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++) {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…
- / In python / def get_new_grades():"""Write a function get_new_grades, such that given a string of grades as an input parameter,returns two objects:the initial grades as a list of numerical valuesas well asa new list with the numerical values, where the scores that are less than 50 are replaced by 50. """ passPublic 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 stringjavascript only: Write a function `popularLetters(string)` that takes a string as an argument and returns an array of all of the characters that appear five or more times in the string. Examples: console.log(popularLetters('apple')); // [] console.log(popularLetters('bananas in pajamas')); // [ 'a' ] console.log(popularLetters('Yes, we have no bananas, we have no bananas today!')); // [ 'e', ' ', 'a', 'n' ]
- 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…Complete the following Java method. This method takes in an array of Strings. The method's task is to find out how many times the most common character frequency appears in all of the array's Strings. As an example, for the array ["mouse", "cat", "dog"], the method should return 9, since the characters "m", "u", "s", "e", "c", "a", "t", "d", and "g" appear only once and this frequency (1) appears 9 times. The character "o", appears twice. This frequency (2) appears only once. Therefore, 9 must be returned. Also, if a character appears multiple times in one String, you must count every occurrence. For example, in the word "houses", the character "s" appears twice. Therefore, each occurrence of "s" must be counted. If there is a tie at the completion of the method, you must still return how many times the most frequent character frequency occurred. Furthermore, in your implementation, you must make use of the Java Class Library's HashMap class in order to map particular characters to…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)
