Fix the indentation errors. Im trying to make a python program for a hashmap but am having errors. The code is almost complete.

for (String name : likedBy) {                    String likedUser= name.trim();                    Set<String> likes = likesMap.getOrDefault(likedUser, new HashSet<>()); Here you create a new Set for likes. This is in the iteration over the likers though so it results in many missing entries.   [  How do i Fix this  ]   import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.util.ArrayList; import java.util.HashMap; import java.util.HashSet; import java.util.List; import java.util.Map; import java.util.Set; public class FacebookLikeManager {     private Map<String, Set<String>> likesMap;     public FacebookLikeManager() {         likesMap = new HashMap<>();     }     public void buildMap(String filePath) {         try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {             String line = reader.readLine();             while (line != null) {                                 String[]…

You may have found it somewhat tedious and unpleasant to use the debugger and visualizer to verify the correctness of your addFirst and addLast methods. There is also the problem that such manual verification becomes stale as soon as you change your code. Imagine that you made some minor but uncertain change to addLast]. To verify that you didn't break anything you'd have to go back and do that whole process again. Yuck. What we really want are some automated tests. But unfortunately there's no easy way to verify correctness of addFirst and addLast] if those are the only two methods we've implemented. That is, there's currently no way to iterate over our list and get bad its values and see that they are correct. That's where the toList method comes in. When called, this method returns a List representation of the Deque. For example, if the Deque has had addLast (5) addLast (9) addLast (10), then addFirst (3) called on it, then the result of toList() should be a List with 3 at the…

The compareTo method. First you compare this.ticker which is a String, then if they are the same then you compare by the this.purchasePrice which is a double hashCode   public int hashCode()   The hashCode method using the Code-> Generate equals and hashCode with no changes   Overrides:   hashCode in class Object   Returns:   int Representing the hashCode   compareTo   public int compareTo(Stock another)   The compareTo method not auto generated Compares first by ticker and if the tickers are the same secondarily compares by price   Specified by:   compareTo" in interface Comparable<stock>   Parameters:   another - the object to be compared.   Returns:   int Representing order   Throws:   IllegalArgumentException"- if another is null.

8.3.2: HashMap with enhanced for loop.   Declare variable scoreToGrade as a HashMap with Character key type and Double value type, representing a grade and the minimum score of the grade. Read integer numToRead from input. Then read numToRead key-value pairs from input and insert each into scoreToGrade. If the key already exists, replace the key's existing value with the new value. Ex: If the input is: 3 D 60.0 A 89.0 A 90.5 then one possible output is: Key: D, Value: 60.0 Key: A, Value: 90.5 Note: The order of the keys is not guaranteed in a HashMap.   import java.util.Scanner;import java.util.HashMap; public class GradeScale {public static void main(String[] args) {Scanner scnr = new Scanner(System.in);char assignedGrade;double minScore;int numToRead;int i;/* Any variable declarations go here */   /* Your code goes here */   // For each key in the HashMap, retrieve the value associated with the keyfor (Character key : scoreToGrade.keySet()) {System.out.println("Key: " + key + ",…

create a script that prompts the user for a number. then create a loop to generate that number of random hash tables. then add these hash tables to an array. powershell

Estimated Completion Time: 2-3 minutes Which of the following situations will lead to an object being aliased? Select all that apply. n Assigning a list to L1, then assigning L1 to L2 n Assigning a string to S1, then assigning the result of slicing S1 (i.e. S1[:]) to S2 n Assigning a list to L1, then assigning the result of a copy() method on L1 to L2 n Assigning a list to L1, then assigning the result of slicing L1 (i.e., L1[:]) to L2 n Assigning a string to S1, then assigning the result of a replace() method on S1 to S2 n Assigning a list to L1, then using L1 in a function call with header "def foo(x: List) -> List" n Assigning a string to S1, then using S1 in a function call with header "def foo(x: str) -> None" n Assigning two lists to L1 and L2, then assigning the result of adding them to L3
