- def swap_text(text): Backstory: Luffy wants to organize a surprise party for his friend Zoro and he wants to send a message to his friends, but he wants to encrypt the message so that Zoro cannot easily read it. The message is encrypted by exchanging pairs of characters. Description: This function gets a text (string) and creates a new text by swapping each pair of characters, and returns a string with the modified text. For example, suppose the text has 6 characters, then it swaps the first with the second, the third with the fourth and the fifth with the sixth character. Parameters: text is a string (its length could be 0)Return value: A string that is generated by swapping pairs of characters. Note that if the Examples: swap_text ("hello") swap_text ("Party for Zoro!") swap_text ("") def which_day(numbers): → 'ehllo'→ 'aPtr yof roZor!' → '' length of the text is odd, the last character remains in the same position.python question: Write a code that takes a sentence as an argument and places its words in a list of words in alphabetical order If the sentence is: "Am I good" The function returns: ['Am', 'I', 'good']public List<String> getLikes(String user) This will take a String representing a user (like “Mike”) and return a unique List containing all of the users that have liked the user “Mike.” public List<String> getLikedBy(String user) This will take a String representing a user (like “Tony”) and return a unique List containing each user that “Tony” has liked. create a Main to test your work. import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;import java.util.ArrayList;import java.util.Arrays;import java.util.HashMap;import java.util.HashSet;import java.util.List;import java.util.Map;import java.util.Set; public class FacebookLikeManager { public List<String> facebookMap; private Set<String> likesSets; public FacebookLikeManager() { facebookMap = new ArrayList<>(); likesSets = new HashSet<>(Arrays.asList("Mike","Kristen","Bill","Sara")); } public void buildMap(String filePath) {…

(b) Describe in words what changes are needed on the above given convert () function so that it…IN JS PROGRAMMING LANGUAGE Your local bank has decided to upgrade its ATM machines by incorporating motion sensor technology. The machines now interpret a series of consecutive dance moves in place of a PIN number. Create a program that converts a customer's PIN number to its dance equivalent. There is one dance move per digit in the PIN number. A list of dance moves is given in the code. Examples danceConvert("0000") danceConvert("3856") ["Shimmy", "Shake", "Pirouette", "Slide"] → ["Slide", "Arabesque", "Pop", "Arabesque" ] -Posted 5th time this question if you submit wrong answer this time will give u a downvote and bad review
- Common Time Zones Function Name: commonTimeZones() Parameters: code1( str ), code2( str) Returns: list of common time zones ( list ) Description: You and your friend live in different countries, but you figure there's a chance that both of you might be in the same time zone. Thus, you want to find out the list of possible time zones that you and your friend could both be in. Given two country codes, write a function that returns a list of the time zones the two countries have in common. Be sure not to include any duplicate time zones. If the two country codes do not have any common time zones, return the string 'No Common Time Zones' instead. Note: You can assume that the codes will always be valid. example test cases: >>> commonTimeZones('can', 'usa') [UTC-08:00', 'UTC-07:00', 'UTC-06:00', 'UTC-05:00', 'UTC-04:00] >>> commonTimeZones('rus', 'chn') [UTC+08:00] For this assignment, use the REST countries API (https://restcountries.com/#api-endpoints-v2).

If the list has an even number of values, the median is the numeric average of the values in the two middle positions. Allow the user to enter 9999 to quit entering numbers. An example of the program is shown below: Enter number 8 or 9999 to quit 10 Enter number 9 or 9999 to quit 700 Enter number 10 or 9999 to quit 9999 size is 9 You entered: 25, 50, 500, 550, 450, 600, 200, The mean is 342.77777777777777 and the median is 450. The example above is abbreviated and included for guidance and does not include all the information generated by the program. Grading !!

Each tuple has two floating point values that are both greater than zero. The first value is the radius r and the second value is the height h. The volume of the cylinder is computed using ??2h. The value π is represented in F# with System.Math.PI. If the list is empty, return 0.0.
