Chapter 8, Problem 24PE

Write a program that fills an integer array of size 1000 with random positive integers between 1 and 10.Assume that each element represents a different city and the integers stored in the array represent thenumber of golds in those cities. The program traverses over the array and collects the golds at each city,starting from a random position. When the program visits a certain city, all of the golds are collected,and the visited element of the array becomes 0 (no gold is left at that city.) The journey continues withthe rule given below. If the position at the nth step is denoted by pn, and the number of golds at the citypn is denoted by gn,??+1 = {| ((??−1 + ?? + ??) ???1000|, ????? 2 = 0| ((??−1 + ?? − ??) ???1000|, ????? 2 = 1.The program continues visiting cities until the last three visited city has no gold.The program, at each visit, should print out the following information:• The current city index (pn).• The previous city index (pn-1).• The number of golds at the current city…

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.

A 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…
