In Python, The function concatAltChars takes a string parameter s and a boolean parameter even; the function concatenates together either the even-position characters of s or the odd-position characters of s, depending on whether even is True, or False, respectively. The accumulated string is returned. For example, the even-indexed characters of "HANOVER" are at indexes 0, 2, 4, and 6: H N V R. So, concatAltChars("HANOVER", True) returns the string result "HNVR". But concatAltChars("HANOVER", False) returns the string result "AOE". For example: Test Result s = "goldfinches" print(concatAltChars(s, True)) glfnhs s = "A" print(concatAltChars(s, True)) A s = "A" print(concatAltChars(s, False))

Implement a function eligible in Python that returns a list of the names of people that are eligible for vaccination, subject to a minimum age requirement. The function eligible must: accept two arguments: 1. the minimum age for eligibility, a positive integer 2. a multiline string, containing the people waiting to be vaccinated. Each line of the stringcontains a person's name and their age, separated by a single space. return a list of the people who are eligible to be vaccinated, i.e., those whose ages is at least that of the minimum age for eligibility. They should be listed in the order they occur in the input string. Sample: >>> people = 'Sue 25\nAli 45\nSyd 45\nSally 105\nIan 16\nUli 65\nOliver 23\nZoe 95'>>> print(people)Sue 25Ali 45Syd 45Sally 105Ian 16Uli 65Oliver 23Zoe 95

Implement a function alterCase in Python that converts a word to "alterCase". Given a word, using any mix of upper and lower case letters, the function then returns the same word, except that the first letter is upper case, the second is lower case, and then cases of letters alternate throughout the rest of the word. >>> alterCase('apple')'ApPlE'

code should be python: write a function that allows the input of a list of strings as its only parameter. Inside the body of the function find the first palindromic word and return it. If there is no such word, it should return an empty string. A string is palindromic if it reads the same forward and backward so for example If we call the function with ["horse", "rat", "roar", "dad", "mom"], the returned value should be "dad". Note that "mom" is also a palindrome, but it is not the first one.

1. a.Palindromes Complete the function palindrome(String text). Return true if text is a palindrome; if the word is identical forward and backward. Otherwise, return false. Example: palindrome("racecar") == true palindrome("kayaks") == false See main() for more examples. You can use text.charAt(i) to find the character at index i of text. Use recursion. palindrome() should call itself. No loops allowed. b. Complete the function nestedBrackets(String s). This function should find properly nested brackets within s. Return true if brackets are opened and closed correctly, and false otherwise. Single pairs and nested pairs are valid. For example: z[z]z, [zz[zz]z], [z[[z]zzz]], zzzzz Incorrect pairings and multiple separate pairs are not valid. For example: zz[zz, ]zzz[, [zzz][z], [z[z][z]z] See main() for more examples. nestedBrackets() should call firstIndexOf() and lastIndexOf() to help you solve the problem. Use recursion. nestedBrackets() should call itself. No loops...

Write a program in Python with a function biggestBuried(s), which the parameter s is a string, and the function returns the largest integer buried in the string. If there is no integer inside the string, then return 0. For example, biggestBuried('abcd51kkk3kk19ghi') would return 51, and biggestBuried('kkk32abce@@-33bb14zzz') would return 33, since the '-' character is treated like any other non digit. print(biggestBuried('abcd51kkk3kk19ghi')) answer should be 51 print(biggestBuried('kkk32abce@@-33bb14zzz')) answer should be 33 print(biggestBuried('this15isast22ring-55')) answer should be 55

1. Divisors: In a class Divisors.java, read in a maximum integer n and use nested loops to print a list of divisors for each of 1 through n as shown in the following transcript. Sample transcript (input underlined): Largest integer? 100 1: 1 2: 1 2 3: 1 3 4: 1 2 4 95: 1 5 19 95 96: 1 2 3 4 6 8 12 16 24 32 48 96 97: 1 97 98: 1 2 7 14 49 98 99: 1 3 9 11 33 99 100: 1 2 4 5 10 20 25 50 100

write a python code named get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary. (Suppose we want to know the total number of cases reported on each date, so use x = 0.) >>> result, total_cases = get_total_cases(database, 0) >>> display_dict(result) 2021年05月19日: 8 2021年05月20日: 2 2021年05月21日: 1 2021年05月22日: 1 >>> print(total_cases)

Implement the following function: Code should be written in python.

PHP Write a wordFilter function Write a function wordFilter($str) that takes a string representing a sentence as a parameter. It should replace all occurrences of certain blacklisted words with asterisks of the same length and return the substituted sentence. The words "shoot" "darn" and "fudge" (case insensitive) are considered blacklisted. However, these words as part of a larger word should be left alone (e.g. overshoot is fine as it is). Use one or more regular expressions with replacements in your solutions (e.g. preg_replace).

Write a function filter_codes(list_codes) that receives a list of codes and returns another list containing those codes that: Only have numeric characters; and Are at least 2 characters long; and At most 6 characters long Hint: remember that Python has a built-in function for determining if a string only contains numeric characters. solve using python
