- An array definition reserves space for the array. true or falseReverse ArrayWrite a function that accepts an int array and the array’s size as arguments. The function should create a copy of the array, except that the element values should be reversedin the copy. The function should return a pointer to the new array. Demonstrate thefunction in a complete program.Java - Functions with 1D Arrays Create a program that asks the user for the size of an integer array and the elements of the array. Then, create a function called maxArray() with the following details: Parameters: An integer array The size of the integer array Return type - int Return value - the maximum value of the integer array Call the function you created in the main and pass the integer array and its size to it. Make sure to store the return value in a variable so you could print it afterwards. Input 1. First line contains the size of the array 2. Succeeding lines are the elements of an array 3. First line contains the size of the array 4. Succeeding lines are the elements of an array 5. First line contains the size of the array 6. Succeeding lines are the elements of an array 7.

- True or False Arrays are reference type objectsX482: Make Perfect Array The mere presence of oversized arrays makes Priscilla Perfect sick to her stomach. Such wasted space is an imperfection she cannot bear. As her oldest and dearest friend this worries you greatly. If you were a doctor you might try to find a cure to her sickness, but you are a programmer. A program must be written to alleviate her pain! For any array given that has empty slots create a new array that is perfect. Unused slots will have a value of 0. All unused slots are guaranteed to be at the end of the array. There will never be unused slots in the middle. java.util.Arrays has been enabled. Examples: makePerfect({1, 1, 4, 5, 6, 0, e, e, 0}) -> {1, 1, 4, 5, 6} makePerfect({1, 3, 4, 2, 6, 0, e, e, 0}) -> {1, 3, 4, 2, 6}The index type of an array may be of any data type. Do you accept this as true?
- Finding the common members of two dynamic arrays: Write a program that first reads two arrays and then finds their common members (intersection). The program should first read an integer for the size of the array and then should create the two arrays dynamically (using new) and should read the numbers into array1 and array2 and then should find the common members and show it. Note: The list of the common members should be unique. That is no member should be listed more than once. Tip: A simple for loop is needed on one of the arrays (like array1) and one inner for loop for on array2. Then for each member of array1, if we find any matching member in array2, we record it. Sample run: Enter the number of elements of array 1: 7 Enter the elements of array 1: 10 12 13 10 14 15 12 Enter the number of elements of array 2: 5 Enter the elements of array 2: 17 12 10 19 12 The common members of array1 and array2 are: 12 10JAVA PROGRAM Chapter 7. PC #16. 2D Array Operations Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods: • getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. • getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. • getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the…2. Intersection Write a method/function that takes two circular arrays, their sizes and start indexes and returns a linear array containing the common elements between the two circular arrays. DO NOT convert the circular arrays to linear arrays to solve the problem. Input: Circular array 1: [40,50,0,0,0,10,20,30] (start_1 =5, size_1 =5) Circular array 2 : [10,20,5,0,0,0,0,0,5,40,15,25] (start_2=8, size_2 =7) Output: [10,20,40] Use Python Language
