Directions: Read each item carefully. Create command/codes based on the information requested on each item. (R programming) Create a list that contains a numeric vector from (1 to 30, 34, 45, 47, and 50 to 70), a character vector that repeat the elements A, B, and C 30 times, and a 2 x 3 matrix that contains a number from 101 to 106 filled by rows.

You are required to: Declare a 4-by-5 array. The array should be initialized with the values as shown in Table 1. Display all the array values as per example in Figure 1. Display the maximum (highest) value as well as the maximum values row and column subscript as per example in Figure 1. Note: Your code should work even if the array is initialized with different values. 15 20 97 4 18 25 4 101 98 105 6 17 2 45 33 88 72 188 34 Table 1 15 20 97 18 25 4. 101 98 105 6 17 2 45 33 88 72 188 34 The maximum value is: 188 This value is found in row 3 column 3 Press any key to continue. ..- Figure 1 Question 3 [43]

Q1: -Write a program that reads from the user a matrix Nx4. The user has to enter students' data in four columns, the first column gets students' names, the second column contains gender, the third column has ages of students, and the fourth column contains the education level. See the example in the figure below. Note that the type of the matrix is string. Ali Ahmed Noor Fatimah www. Male Male Female Female 17 21 20 25 1st 4th 3rd 3rd 24 ** 1. Find How many females and males are in the matrix. 2. Find how many male students their ages are above 25 years. 3. Find how many students in the 1" year who their ages are 17 years.

True or False The subscript of the last element will always be one less than the array’s Length property.

City Location (definition of simple cell array) The city of Istanbul, Turkey is located at a latitude of 41.0082 degrees north and longitude of 28.9784 degrees east. Write a script to do the following: 1. Define a character array variable named CityName and assign the value 'Istanbul, Turkey' to it. 2. Define a single precision two-element row vector named LatLong and assign the latitude of Istanbul to the first element and the longitude of Istanbul to the second element. 3. Define a 1 x 2 cell array named CityLocation. Assign the character array 'Istanbul, Turkey' to the first cell. Assign the single precision row vector of Istanbul's latitude and longitude to the second cell.

part a- 2point) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Part b- 1 point) Find the maximum and minimum grades for each student. Part c- 1 point) Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98 (Array not vector)

Given E[3][4], α=2020, esize=4 bytes:a) Find the total no. of elements.b) Find the address of the last element.c) Find the address of the 10th element.

4. Array code Fill in the method below to have it create and fill in an array of 4 doubles. The first ele- ment should be set to the average of the first quarter of the array passed to data, the second element should be set to the average of the second quarter of the array, and so on. If input data is [1, 2, 3, 4, 5, 6, 7, 8] result should be [1.5, 3.5, 5.5, 7.5] public static double[] quartileAverages(int [] data) {
