- Write a program that reads in ten numbers and displays the number of distinct numbers and the distinct numbers separated by exactly one space (i.e., if a number appears multiple times, it is displayed only once). (Hint:Read a number and store it to an array if it is new. If the number is already in the array, ignore it. While solving the question please use an array.) After the input, the array contains the distinct numbers. Here is the sample run of the program: Enter ten numbers: 1 2 3 21634 5 2 The number of distinct number is 6. The distinct numbers are: 123645arrow_forwardA scientist has developed a mathematical model for a physical process, and he wants to check how good is model is. To evaluate the correctness of his model, he wants to test the results of his model under certain parameters and compare them with experimental results. Write a program that first reads the number of tests (testCount) as an int followed by the results of each test according to the model as a double array (test Model) and finally the results of each test according to experiments as a double array (testExperiment). Then, the program should calculate the error of the model by evaluating the average of the squares of the differences between the model result and experimental result (see formula below) using a function. Error Input 1 testCount NOTE: Individual square of the difference between the model value and the experiment value calculations MUST be done in the function. Every other functionality MUST be done in the main function. NOTE: To calculate square of a number you…arrow_forwardWrite a program in c that create a 5-by-6 array. All elements in the array are random integer numbers between 1 and 100. Then, calculate the mean values of each column, and also find the minimums and maximums of each column. Print out the array, mean values, minimums,arrow_forward
- PROGRAM in JAVA Write a program that defines two arrays - one of strings and one of integers, both of size 10. Your program should then ask the user to enter the a string representing a persons name (just one name - their family name - not their given name as well), and an integer representing their age. It should continue to do this until either the user enters ‘done’ instead of a name, or until the array is full (that is, 10 pairs of names and ages have been entered). It should then print out the names and ages as well as the names of the youngest and oldest. Hints: One tricky (deliberately) part is making sure that once you’ve typed ‘done’ to finish entering names, your program does not then ask you for the age of the person with name ‘done’ - be careful about this. This is one of the few cases where, if you are careful, you can sensibly use a ‘break’ statement outside of a switch statement Stage 6: Assessed Task Redo Stage 5 above but replace the arrays with ArrayLists.arrow_forwardWrite a program that lets the user enter the total rainfall for each of 12 months into an array of doubles. The program should use two 12-element arrays. One array will hold strings, the names of the 12 months. This array will be initialized when the array is created using an initialization list (could also be created as an array of constants). The second array will hold doubles which will be the total rainfall for each month. The program will prompt the user for the rainfall for each month (using both arrays) and store the value entered into the array with the rainfall totals; the other is used to display which month the program is asking for the rainfall total. The program should display the following once the data is all entered: The total rainfall for the year The average monthly rainfall The month with the highest amount of rainfall (must display the month as a string) The month with the lowest amount of rainfall (must display the month as a string) The program must have the…arrow_forwardQ3. Given an array of integers of an arbitrary number of elements, write a program that creates an array with the elements "rotated left" according to an integer denoting the shift. so [1, 2, 3] with shift 1 yields [2, 3, 1] and [1, 2, 3] with shift 2 yields [3, 1, 2].arrow_forward
- 1. Write a program that fills an array with 10 random integer values between O and 100, your program should then calculate and print the alternating sum of all elements in the array. for example, if the array values are (89, 35, 44, 61, 66, 52, 45, 16, 48, 73) then the sum will = 89- 35 + 44 - 61 + 66- 52 + 45 - 16 + 48 - 73 = 55. Sample Run: The generated numbers are: 2 11 44 38 66 72 38 67 43 13 The alternating sum is -8 2. Write a program that reads 10 characters from user and store them in an array. Then display one or more of the following messages: 1. All characters are letters 2. All letters in the list are upper 3. There is no vowel letter in the list 4. There is at least 2 digits in the list 5. There is at least 3 symbols in the list Sample run 1: Enter 10 characters: AB1OK8 M& ? All letters in the list are upper There is at least 2 digits in the list There is at least 3 symbols in the listarrow_forwardExercise 1: Write a program that generates a sequence of 20 random values between 0 and 99 in an array, prints the sequence, sorts it, and prints the sorted sequence. Use the sort method from the standard Java library. Exercise 2: Write a program that stores a list of countries: "Egypt", "Switzerland", "Argentina", "Spain", "Portugal", "Luxemburg", etc. Initialize your array with a single statement. Then print out the array. Use the sort function as before to sort the countries in alphabetical order. Reprint your array. Exercise 3: Implement exercises 1 and 2 using ArrayList. Use the Collections.sort method for sorting. After you have printed and sorted your results, then append an additional element to each list and reprint your ArrayLists. Notice that the new items will appear just at the end and will not be sorted. Resort and print out the new ArrayLists again. To clarify, you should print out your ArrayLists after your first sort, after adding items with the…arrow_forwardWrite a program that creates and initializes an array with the following four values: 2.3, 4.5, 8.0, and 2.1.

For example, consider the tablebelow: A two dim table with 10 rows and 2 columns can be used to represent the percent ofwomen and percent of men for each major.The name of the majors can be stored in a one dimensional array of Strings.There are other better ways to represent the information but for now this will donicely.3) The program should print a line explaining what the data in the array represents.4) Print the information in table format.5) In a comment, cite the source of the informationarrow_forward
