m Description: Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to the target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer i

Problem 1: Complete the sumOfDiagonals method in SumOfDiagonals.java to do the following: The method takes a 2D String array x as a parameter and returns no value. The method should calculate and print the sum of the elements on the major diagonal of the array x. In order to have a major diagonal, the array passed into the method should be a square (n-by-n), if it's not a square your program should handle that situation by throwing an exception. (Do Not worry about ragged arrays) If the array is a square, but there is a non-integer value on the major diagonal, your program should handle that situation by throwing an exception. When handling the exceptions, be as specific as you can be, (i.e. Do Not just use the Exception class to handle all exceptions in one catch block). Make the proper calls to the sumOfDiagonals method from the main method to test your sumOfDiagonals method on all the String arrays provided in the main method.

You have made a device that automatically measures both distance from a magnet and the magnetic field strength at that distance. The device sends the pair of data to your computer as a pair of real numbers. However, the device moves back and forth as it takes data, so neither the field measurement nor the distance measurement arrives in ascending or descending order. Write a code vector_sort that receives a two-dimensional array of numbers and sorts them based on either the first column or the second column (this must be an input to the function. The function must also either sort high-to-low or low-to-high, based on an input value. Write a main function that can read up to twenty pairs of data. The main function must also input whether you want to sort high-to-low or low-to high. It must also input whether you want to sort on magnetic field or distance. Finally the code must print the pair data as originally entered and then, after calling vector_sort, the ordered pair data. C Program

An array int[] intArray can be initialized during its definition by A.) It can't be initialized B.) by writing int[] intArray = {1.0f}; C.) by writing int[] intArray = {0,1,2}; D.) by writing int[0-10] intArray = {0,1,2,3,4,5,6,7,8,9};

1. Array splitting in Java Create an integer array with 10 integer numbers, initialize the array arbitrarily but make sure there are both positive and negative integers. Then generate two arrays out of the original array, one array with all natural numbers (positive numbers or zeros) and another one with all negative numbers. Print out the number of elements and the detailed elements in each array.

mergeAndRemove(int[], int[]) This is a public static function that takes a int[] and int[] for the parameters and returns an int[]. Given two arrays of integers. Your job is to combine them into a single array and remove any duplicates, finally return the merged array.

//convert array of numbers from farenheit to celcius// example:// argument: [23, 32, 41, 50, 59]// return: [-5, 0, 5, 10, 15]// hint: use Array.mapfunction toCelcius(array){ } //write a function that takes an input array and returns an array of booleans (>=75) or fail (<75)// example:// argument: [20, 30, 50, 80, 90, 100]// return: [false, false, false, true, true, true]// hint: use Array.mapfunction passOrFail(array){ }

void changeAll(int x[]) { x[0] = x[0] + 5; return; The first element in an array would be increased by 5 The array would be the same because it was passed by value x would be increased by 5 All the elements in the passed array would be incremented by 5

In Java Assignment 5B : Maze Game! 2D Arrays can be used to store and represent informationabout video game levels or boards. In this exercise, you will use this knowledge tocreate an interactive game where players attempt to move through a maze. You willstart by creating a pre-defined 2D array with the following values:{"_","X","_","X","X"}{"_","X","_","X","W"}{"_","_","_","X","_"}{"X","X","_","_","_"}{"_","_","_","X","X"}You will then set the player (represented by "O") at index 0, 0 of the array, the top-leftcorner of the maze. You will use a loop to repeatedly prompt the user to enter adirection ("Left", "Right", "Up", or "Down"). Based on these directions, you will try tomove the player.• If the location is valid (represented by "_"), you will move the player there• If the location is out of bounds (e.g. index 0, -1) or the command is invalid, youwill inform the player and prompt them to enter another direction• If the location is a wall (represented by "X"), you will tell the...

Bonus Question: For the same array as in the last question, explain what this statement does: x = &x[2]; Hint: draw a memory diagram to help yourself find the correct answer.
