please help me public static void main(String args[]){ int[] x={1,4,88,9,13,77,4,18}; for(int i=0;i<x.length;i++){ for( int j=i+1;j<x.length;j++){ if(x[i]==x[j]){ System.out.println("duplicates exists is : "+x[i]); }}} System.out.println("no duplication"); } The above segment of code is searching the duplicated values inside an array, where the complexity is O(n). Suggest another solution for the above problem with less time complexity.
in java Create two arrays with same length n: - Array A with integer numbers that user will insert- Array B with random numbers from 0 to 100.- Find sum of both arrays,- Find maximum values of both array and compare them: .if maximum of 1 st is lower then maximum of 2nd array: print sums of both arrays.if maximum of 1st is greater then maximum of 2nd array print 2nd array (use println)otherwise print first array in reverse.
Requirements: Use Java Programming only. Show screenshots of your work. this is the second time I posted this since the previous answer is very wrong. 6. Write method public static int linearSearch(int [] arr, ine key) which returns the largest index such that arr[index] matches the key. If there is match, returns -1. 7. Write method public static double average(int [] arr) which returns the average of all elements in given array arr. Assume that arr has length at least 1. 8. Write method public void crazyPrint(String sentence, int n) which print out the given sentence n times. Assume n is positive integer.
Which shows valid accesses for an array a and vector v, each with 10 elements? In other words, this question is asking what is the proper syntax for accessing the array and vector. a. array: a[7] vector: v.at(5) b. array: a.at(5) vector: v[9] c. array: a.at(5) vector: v[5] d. array: a[1] vector v.at[4] Coding is in C++.
Instrument shellsort to print the number of compares divided by the array sizefor each increment. Write a test client that tests the hypothesis that this number is asmall constant, by sorting arrays of random Double values, using array sizes that areincreasing powers of 10, starting at 100
In the following code both myList and yourList are dynamic arrays of the same size. The code initializes the array myList to certain values. The value in each element of yourList should be twice the value in the corresponding element in myList. However, the output of this code would show that is not the case. Provide the correct code to accomplish the desired results. int *myList;int *yourList;myList = new int[5];myList[0] = 8;for (int i = 1; i < 5; i++)myList[i] = i * myList[i - 1];yourList = myList;for (int i = 0; i < 5; i++)yourList[i] = 2 * myList[i];
The following program AverageTest calculates and prints the average of all elements of an int array.

(IN JAVA) Implement a mergeUniqueValues(arr1, arr2) method. When passed two arrays of strings, it will return an array containing the strings that appear in either or both arrays in sorted order. And the returned array should have no duplicates. For example, if you have two string arrays: arr1: {“Bear”, “Elephant”,”Fox”}arr2: {“Panda”, “Elephant”,”Eagle”} Calling mergeUniqueValues(arr1, arr2) should return a merged and sorted array like: Bear, Eagle, Elephant, Fox, Panda
In Python, Define and invoke using chain function calls, the myArange() and myReshape() methods in one line of code as shown in the figure below, and use a for loop to place one element at a time from the 1D array into the 2D array. a = myClass() rows = int(input('Enter the number of rows: ')) columns = int(input('Enter the number of columns: ')) arrMain = a.myArange(1,16).myReshape(rows,columns)
. Now take any name from the user, find whether that name is present in that array or not, and print the position of that name in the array if found. Write a search method to sequentially search the name from the array. Invoke the search method from the main method. The array and the name to be searched should be passed into the search method as parameters.Now write a Java program to implement binary search for the above problem.[Hint: You can use equals() and compareTo() methods of String class.]
