Retrieving a value using its associated key can be accomplished using an indexer, which works just like an indexer for an array. A key is passed in as the index value, and the value associated with the key is returned, unless the key doesn’t exist, in which a null is returned. Write short code segment demonstrates how this technique works:

Method Implementation Design and implement a method to swap the first and the last element of an array. For example, 1 4 9 16 25 would be transformed into 25 4 9 16 1. Important: You don’t need to test this method in main(). You don’t need to initialize the array. You don’t print out the values in the method. All you need to do is swap the first with the last element. pubilc static void swapFirstLast(int [] arr) {
The array index can be any integer less than the array size… TRUE OR FALSE
2DArray method:It will allocate a block of memory which represents a two-dimension arraybased on the input values supplied by the user. Ask the user to enter the number of rows andcolumn for 2D array that the user want to manipulate. The number of rows and columns that theuser enters may or may not define a square matrix (when the number of rows equals the numberof columns). The array will have exactly rows time columns (m * n) elements. It will notcontain any extra or empty cells. Initialize the “matrix” by rows with random number between 1to 100. Pass two arguments by out reference so that you can assign the number of row andcolumns of data to the first and second arguments. This is return 2D array method afterallocating new memory for 2D array and initialize it with random value. Generate randomnumber code in C# as following: Random randnum = new Random( );int number = randnum.Next (1, 101);SwapRow method: it will rotate the data in the matrix in an up/down method such that the…
continue from first question, Client class:The client program will allow entry of these data for several different student into an ArrayList and then perform some analysis and queries.Your client class (program) will provide the user with a menu to perform the following operations. You will also need to load the information of the students from a CSV file (student.csv) before displaying the menu. You only need one ArrayList and one menu for this. For the csv file, your first item can be U or G to differentiate whether the entry is creating a UndergraduateStudent object, or a GraduateStudent object. You can then decide how you want other data to be listed in the csv file. You should specify clearly in your documentation the data format of the CSV files used in this assignment.1. Quit (exit the program)2. Add (to the ArrayList) all the marks information about an undergraduate or graduate student by reading it from another CSV file. Your program will ask for the file name.3. Given student…

Task 01: Assume P(x,y) is (x+y>4). Write a function/method that can validate the nested quantifier Vy P(x,y) for elements from two arrays X and Y. i. hint: The method returns l if statement is valid (the sum of all pairs of values from X and Y is greater than 4), and returns 0 otherwise. Valid case: For arrays X={2,3,4} and Y={3,4,5), the method returns 1(since xEX and býyEY, xi+y>4) Invalid case: For arrays X={2,3,4} and Y={1,4.5}, the method returns 0 (since 2EX and l EY but 2+1<4)
Problem2 Write a program that display the position of a given element in an array. You should print the index (i.e. the position) of the element. If the element appears more than one time than you should print all its positions. The size of the array should be entered by the user. If the element does not occur then you should display element not found. Sample1: Enter the size of the array: 5 Enter an array of size 5: 44 5 13 44 67 Enter the element to find: 44 44 is found at position 44 is found at position 44 occurs 2 time(s) Sample2: Enter the size of the array: 4 Enter an array of size 4: 12 150 17 20 Enter the element: 18 18 is not found
Create an indexception value of unique consonants and unique vowels.This is the Input: String of the name that was given below. It must be case sensitive.Steps:Step A: In every unique vowel of a name, you need to get the first index of that vowel from the original string.Step B: In each vowel index you get from step A, you will get the unique consonant from that position. if the index is out of scope of the consonant array, ignore that vowel index.Step C: In each unique consonant that you get from step B, you need to get the first index of that consonant from the original string.Step D: You will the value of indexception by adding all index you get from step C.output must be like this: > 2 lists that consist of unique vowels and unique consonants> vowel, the vowel index, the consonant, the consonant indexfinal ouput> total indexception value of the name that was given. ------Input "Tricia O.

Exo 9: The user will klrite an algorithm that allows the user to remove a value from a previously entered array, give the index of the value be wishes to detete. Attention! it is not a question of resetting a value to Zero, but rather of deleting it from the table. itself! If the starting table was: 8 4 45 64 9 And the user wants the Index Value, 4, the new array will be: 12 8 H 45 9
The index type of an array may be any kind of data. Do you believe this to be true?
create an INDEXCEPTION value of the unique vowels and unique consonants that the name that was given to you can create. Use python processStep 1: For every unique vowel of a name, you need to get the first index of that vowel from the original string.Step 2: For each vowel index you get from step 1, you will get the unique consonant from that position. if the index is out of scope of the consonant array, ignore that vowel index.Step 3: For each unique consonant that you get from step 2, you need to get the first index of that consonant from the original string.Step 4: Get the value of indexception by adding all index you get from step 3.outputTO BE DISPLAYED- 2 lists that consists of unique vowels and unique consonants- The vowel, the vowel index, the consonant, the consonant indexFINAL OUTPUT- The total indexception value of the name that was given to you.
