An array can be used to store large integers one digit at a time. For example, the integer 1234 could be stored in the array a by setting a[0] to 1, a[1] to 2, a[2] to 3, and a[3] to 4. However, for this exercise you might find it more useful to store the digits backward, that is, place 4 in a[0], 3 in a[1], 2 in a[2], and 1 in a[3].
In this exercise you will write a
After they are read into the program, the characters are changed to values of type int. The digits will be read into a partially filled array, and you might find it useful to reverse the order of the elements in the array after the array is filled with data from the keyboard. (Whether or not you reverse the order of the elements in the array is up to you. It can be done either way, and each way has its advantages and disadvantages.)
Your program will perform the addition by implementing the usual paper-and- pencil addition

- Write a program to enter 10 numbers using keyboard and put them in an array.Now generate another array of same size from the array created in the first stepby satisfying the following conditions: If the number is prime then write ‘P’ to the same location of the secondarray If the number is divisible by 5 then write ‘F’ If the number is divisible by 3 then write ‘T’ If number is an Even number and neither divisible by 3 or 5 then write‘E’ If number is an Odd number and a non-prime number write ‘N’arrow_forwardWrite a Java program with a single-dimension array that holds 10 integer numbers and identify the maximum value of the 10 numbers. Next sort the array using a bubble sort and display the array before and after sorting. Psuedocode Generate 10 random integer numbers between 1 and 100 place each random number in a different element of a single-dimension array Display the array's contents unsorted as they are generated Using the bubble sort, sort the array from smallest integer to the largest. //must use the following: Bubble Sort Code: public static void bubbleSort(int[] list) { int temp; for (int i = list.length - 1; i > 0; i--) { for (int j = 0; j < i; j++) { if (list[j] > list[j + 1]) { temp = list[j]; list[j] = list[j + 1]; list[j + 1] = temp; }…arrow_forwardAn array having a character subscript can be indexed using a computer language, as in CHR_ARRAY['A':'D']. In this scenario, the characters' ordinal numbers (ORDs), such as ORD('A') = 1, ORD('B') = 2, ORD('Z') = 26 and so on, are used to designate the array's elements, CHR_ARRAY['A'], CHR_ARRAY['B'], and so on. Beginning at position 500, two arrays called TEMP[1:5, -1:2] and CODE['A':'Z', 1:2] are now kept in the RAM. Furthermore, CODE outperforms TEMP in storage. Determine the locations of the following addresses: (i) TEMP[5, -1], (ii) CODE['N',2], and (iii) CODE['Z',1].arrow_forward
- Write a python program to print the prime numbers existing in an array. For instance, if A = [4, 7, 12, 3, 9], the output should be 7, 3.arrow_forwardWrite a Java program using a one-dimensional array that accepts as input an integervalue asking for the number of elements for each list. This will be used to generate randomnumbers (5 to 69) for the one-dimensional arrays (List A and List B). The program willcompute for the product and store it in another array (List C).arrow_forwardWrite java program to create one dimensional array (MyList) of size 10, initialize its first two elements by reading them from the keyboard. Use for loop to fill its other eight elements such that each element is the sum of the previous two elements (i.e. the third element is the sum of first element and second element, and so on). b) Write two methods, the first one to calculate and print the sum of even numbers in the above (MyList) array. The second is to calculate and print the count of odd elements in (MyList) array. c) Answer the following questions: a. Print all elements of the array (MyList) such that each line has only three elements (two elements with its sum). b. Create a java program that enable you to check if an integer number is divisible by 7 and 9, and also if it’s divisible by 7 or 9 but not both.arrow_forward
- You have an array with all the numbers from 1 to N, where N is at most 32,000. The array may have duplicate entries and you do not know what N is. With only 4 kilobytes of memory available, how would you print all duplicate elements in the array?arrow_forwardWrite a program to do the following with a 2D Array IN JAVA: Create an integer array of 10 rows and 5 columns Load the array with random integers: On the first run use a range of 1-100 On the second run a range of 100 – 500 On the third run a range of your choice. Sum the elements of the array into a new array Sum the rows only also to a new array Output the array as a matrix Sort the data of the array and output the sorted data Search for a value based on the above ranges and as requested from a user.arrow_forwardYou have an array with all the numbers in it, starting at 1 and going up to a maximum of 32,000. You don't know what N is, and the array could include duplicate elements. How would you publish every duplicate entry in the array if you had just 4 kilobytes of memory?arrow_forward
- input an unsorted array A of n number and an integer k with 1<= k <= n. output an array B of size k that contains the k largest numbers in A with B[1] >= B2....>=[k] index of the array starts from 1 1. write algorothim pseudocode. analyze the bestcase .k . analyze the worse case of k.arrow_forwardWrite a java code that computes the alternating sum of all the elements in an array. For example, if your program has an array with these elements. 1 4 9 16 9 7 4 9 11 It will compute: 1 - 4 + 9 - 16 + 9 - 7 + 4 - 9 + 11 = -2arrow_forwardYou can see in the above display, we first sort each row of the 2D array; we then take the transpose of a two D array, i.e., all the row elements becoming the column elements; we then sort each row of the 2D again. If you read the final array, each row is sorted; each column is also sorted. The smallest element obviously is the 1st element of the two D array and the last element is the largest element of a two D array. Let us now look at the following UML diagram: (Note that additional methods are allowed; proposed methods and instance variable cannot be changed) Main method firstly constructs a 2D array of certain sizes and then construct a TwoD object and drive the task according to the above runtime interactions and displays. TwoD class has only one instance variable which is a two D array of numbers ( int or double). The constructor must do some “deep” copying. A copy constructor. The other three methods are obvious in definition: to sort each row, to rotate the 2D array (i.e.,…arrow_forward
