Sales.java contains a Java program that prompts for and reads in the sales for each of 5 salespeople in a company. Now modify the program as follows: Declare an array called sales to save the sales of 5 salespeople. Complete the header of the first for loop. This loop initializes the array. Complete the header of the second for loop. This loop computes the total of array elements. Add code to compute and print the average sale. Add another loop to print the id of each salesperson and the number of their sales. The salespeople are objecting to having an id of 0—no one wants that designation. Modify your program so that the IDs run from 1-5 instead of 0-4. // *************************************************************** // Sales.java // // Reads in and stores sales for each of 5 salespeople.

Peaks and Valleys: In an array of integers, a "peak" is an element which is greater than or equalto the adjacent integers and a "valley" is an element which is less than or equal to the adjacentintegers. For example, in the array {5, 8, 6, 2, 3, 4, 6}, {8, 6} are peaks and {5, 2} are valleys. Given anarray of integers, sort the array into an alternating sequence of peaks and valleys.EXAMPLEInput: {5, 3, 1, 2, 3}Output: {5, 1, 3, 2, 3}
Java Program Your program should use 2D arrays to implement simple matrix operations. Your program should do the following: • Read the number of rows and columns of a matrix M1 from the user. Use an input validation loop to make sure the values are greater than 0. • Read the elements of M1 in row major order • Print M1 to the console; make sure you format as a matirx • Repeat the previous steps for a second matrix M2 • Create a matrix M3 that is the transpose of M1 and print it to the console • Check if M1 and M2 can be added (should have the same dimensions). If possible, add M1 and M2 and print the result to the console. Otherwise print an error message. • Extra credit: Multiply M1 and M2 if possible and print to the console. If the matrices cannot be multiplied, print an error message. Implementation requirements: • Use a helper method for reading a positive integer using an input validation loop. • Use a helper method for printing a matrix. Your helper methods should be private and…

Best Partition You are given an array of positive numbers of size N and an integer K. You need to partition the array into K continuous segments. For each segment, the sum of its elements needs to be calculated. The segment with the minimum sum is called the bestSegment and the sum of the elements of the bestSegment is called the bestSum. For all possible combinations of partitions of the array when divided into K segments, their bestSum needs to be calculated and the one among them with maximum value needs to be returned. Input Specification: input1: an array of N positive numbers input2: an integer N denoting the length of the array input3: an integer K Output Specification: Return an integer denoting the maximum value of all possible bestSum. Example 1: input1: (1,2,3,4} input2: 4 input3: 2 Output: 4 Explanation: You can partition the given array into 2 continuous segments in the following manner- • 123 14- the sum of individual segments is (6,4) and the bestSum is 4 • 12134- the…
Lab Goal : The lab was designed to teach you how to use arrays to simplify solving more complex problems. Lab Description : Given a provided array, determine how many groups of a specified size exist.For the array [1,1,1,2,2,2,3,3,3,4,5,6,7] , there are 7 groups with at least one, 3 groups with at least 2, and 3 groups with at least 3. A group is a series of same values. 1 1 1 is a group of 3, but it also is a group of 1 and 2. To count as a group, all values must be the same. 1 1 1 is a group of 3 because there are 3 1s in a row.Sample Data : 3 3 3 3 3 9 4 4 4 5 5 5 5 6 6 7 7 7 8 8 8 8 8 8 8 8 1 2 3 4 5 6 7 8 9 1 1 1 2 1 1 3 3 3 3 3 3 3 3 3 3 4 4 4 5 4 4 4 6 Sample Output : [3, 3, 3, 3, 3, 9, 4, 4, 4, 5, 5, 5, 5, 6, 6, 7, 7, 7, 8, 8, 8, 8, 8, 8, 8, 8]size 1 count == 7size 2 count == 6size 3 count == 5size 4 count == 3size 5 count == 2size 6 count == 1 [1, 2, 3, 4, 5, 6, 7, 8, 9]size 1 count == 9size 2 count == 0size 3 count == 0size 4 count == 0 [1, 1, 1, 2, 1, 1, 3, 3, 3, 3, 3, 3, 3,…
