### Implementing the Index-Based `get` Method in an Array-Based ListWithin the `ABList`, the `numElements` variable holds the number of elements currently in the list, and the `elements` array stores those elements. Assuming that a legal index is used, we need to determine the code for the index-based `T get(int index)` method. Here are the options provided:1. `return elements[index];`2. `return index;`3. `T value = elements[index]; return T;`4. `return elements[index].getInfo();`5. `None of these is correct`#### Explanation of the Options:- **Option 1: `return elements[index];`** This option directly returns the element at the specified index from the `elements` array. This can be a valid way to get an element from the list.- **Option 2: `return index;`** This option simply returns the index itself, which does not fulfill the requirement of fetching the element from the list.- **Option 3: `T value = elements[index]; return T;`** This option attempts to store the element at the specified index in a variable `value` of type `T`. However, it mistakenly returns `T` instead of returning the variable `value`.- **Option 4: `return elements[index].getInfo();`** This option assumes that each element in the `elements` array has a method `getInfo()`. This might not be applicable in the general case unless `T` is a class that has the `getInfo()` method.- **Option 5: `None of these is correct** This identifies that none of the above options are correct if we're following standard practices or specific requirements not mentioned here.After evaluating the options, **Option 1** (`return elements[index];`) is the most plausible and correct code that represents the index-based `T get(int index)` method for an array-based list, provided the index is legal.

Recall that within the ABList the numElements variable holds the number of elements currently in the list, and the elements array stores those elements. Assuming that a legal index is used, which of the following represents the code for the index-based T get(int index) method? O return elements[index]; O return index; OT value = elements[index]; return T; O return elements[index].getInfo(); O None of these is correct

*IN C++ A handy feature of lists in Python is that you can use negative indices to get at elements starting from the very end. For example, x[-1] returns the last element in x, x[-2] returns the penultimate element, etc. Implement a struct named "PythonicIntVector" in the files "PythonicIntVector.h" and "PythonicIntVector.cpp" that supports the push_back and at methods of a vector of ints. However, be sure to add the functionality of negative indices. Don't forget that the at method still should throw exceptions for invalid indices (just like in Python)!

If N represents the number of elements in the collection, then the contains method of the ArrayCollection class is O(1). True or False If N represents the number of elements in the list, then the index-based add method of the ABList class is O(N). True or False
Remove Char This function will be given a list of strings and a character. You must remove all occurrences of the character from each string in the list. The function should return the list of strings with the character removed. Signature: public static ArrayList<String> removeChar(String pattern, ArrayList<String> list) Example:list: ['adndj', 'adjdlaa', 'aa', 'djoe']pattern: a Output: ['dndj', 'djdl', '', 'djoe']

] ] get_nhbr In the cell below, you are to write a function called "get_nhbr(Ist, graph)" that takes in two inputs: a list of vertices and a graph. The function is to return a list that contains the neighborhood of the vertices in 'Ist' (remember that this means you are finding the union of the individual vertices' neighborhoods). + Code + Markdown After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (get_nhbr(["A", "D"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]}), get_nhbr(["B", "C", "F"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]})) This should return ["B"] ["A", "D", "E"] Python Python

remove_from_list(my_list, indices): Takes two lists as input. Creates a new list from the first input list by removing the elements at indices given by the integers in the second input list, then return the new list. The indices in the second input list may have any order. For example, if the first input list is [4, 8, 12, 161, and the second input list is [0, 2], then the new list returned from the function should have the 4 and the 12 removed, because they were at indices 0 and 2 of the original list. Note: You do not need to consider negative indices for this function. >> remove_from_list(['abc', 'def', 'ghi'], [1]) ['abc', 'ghi'] >>> strs = ['The', 'quick', 'brown', 'fox'] >>> remove_from_list(strs, [0, 3]) ['quick', 'brown'] >>> strs ['The', 'quick', 'brown', 'fox'] # original list is unchanged >> remove_from_list(['The', 'quick', 'brown', 'fox'], [3, 0]) ['quick', 'brown'] find_last(my_list, x): Takes two inputs: the first being a list and the second being any type.
