- In java Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8, 1, 4, 6}, the function would return 6, since the subsequence {1, 4, 6} is the longest that is strictly increasing. Develop a function that takes a string…What benefits do enumeration types provide over a collection of named constants? What benefits does a subrange type have over its base type? When might a string be preferable over a character array?5.24 LAB: Shift right (JAVA) Write a program in java that reads a list of integers from input into an array and modifies the array by shifting each element to the right one position and by shifting the last element to the first position. The input begins with an integer indicating the number of values that follow. Output the modified array and end with a newline. Ex: If the input is: 6 2 4 6 8 10 12 the output is: 12 2 4 6 8 10 For coding simplicity, follow every output value by a space, including the last one. Code starts here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int[] userValues = new int[20]; // List of integers from input /* Type your code here. */ }}
- JAVASCRIPT Write the function divideArray() in script.js that has a single numbers parameter containing an array of integers. The function should divide numbers into two arrays, evenNums for even numbers and oddNums for odd numbers. Then the function should sort the two arrays and output the array values to the console.Code an exam in Java that repeatedly asks the user to enter the capital for a province in Canada. Then, the program should report whether the answer is correct. Eventually, you must display how many answers the user guessed correctly.The requirements are as follows: - Use a 2D array to hold the provinces and their capitals (as implied by the table below)- Answers are not case-sensitive (e.g. Toronto and tOrOnto are considered the same)In java: Develop a function that accepts an array of integers and returns their average. Develop a function that accepts an array of integers and a threshold value from the user. The function returns how many values in the array are strictly greater than the cutoff. Using the functions written for #1, #3, and #4, find the number of values above average in two randomly generated arrays. Develop two functions:a. a function that returns the index of the maximum value in an array of integers passed by a caller, the caller prints the returned index and the value at that indexb. a function that returns the index of the alphabetically first value in an array of strings, the caller prints the returned index and the value at that inde Develop two functions:a. a function that swaps the alphabetically first value in an array of Strings with the first value in the array. Call this function twice on two different arrays of Strings; in the caller, use the function written for #2b to display…
- Your Friendly Array Neighbor Program only in java not in python Create a Java program that takes an array called ar as an input that keeps track of arrays. Every day a new array is produced using the array of the previous day. On the n’th day, the following operations are performed on the array of day n – 1 to produce the array of day n: -If an element is smaller than both left and right neighbor, then this element is incremented -If an element is bigger than both its left neighbor and its right neighbor, then this element is decremented. -The first and last elements should never change Eventually after some days the array will not change, some examples: Example: Input from user: ar = [6,2,3,4] Output from program: [6,3,3,4] After the first day the array is changed from [6,2,3,4] to [6,3,3,4] and no further operations may be completed. Example: Input from user: ar = [1,6,3,4,3,5] Output from program: [1,4,4,4,4,5] After the first day the array is changed from [1,6,3,4,3,5]…Student class is defined as follows. Class Student {int Number String Name} Using the “Student” class write a Java program that reads student’s data on the screen into one dimension array. List the data that you read in array. Test your program for 10 students and show the result list. Note: Just use one array.using java programming int a[] = {5,10,4,20,1,7}; 1- search for the smallest element in array 2-if you found the smallest element in the array :swap the first element with the smallest element
- In Java List all the values of the array after the function is called static void Fun(int[][]list){ int temp=list[1][2]; list[1][2]=list[0][2]; list[0][2]=temp; }Language: C++ (Words in bold is code) Explain your answer. True or False? - After the following lines of code are executed, the pointer John is pointing to null. Person* John = new Person(); delete John;In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…
