What is the time complexity associated with accessing a single value in an array? The Vector class is clearly more complex than the array. What is the time complexity of accessing an element with the get method?

Complete the method endsInFive that takes as arguments a 2D-array of integers and an integer value that represents a column index in the array. endsInFive returns the number of values in the column that end in 5. It is possible that the array is ragged, meaning that the number of columns in each row is different. For example, 2 is returned if the following 2D-array is passed as the first argument of endsInFive and the integer 3 as the second argument (the values 25 and 115 end in five at column index 3).

Write a simple java delcaration for an array of double values name a. Do not allocate space for the elements of the array.

Compare and contrast the array and arrayList. Give at least one example that describe when to use arrayList compared to an array.

Modify the quick sort implementation in the textbook to sort the array using pivot as the median of the first, last, and middle elements of the array. Add the modified quick sort implementation to the arrayListType class provided (arrayListType.h). Ask the user to enter a list of positive integers ending with -999, sort the integers, and display the pivots for each iteration and the sorted array. Main Function #include <iostream>#include "arrayListType.h"using namespace std; int main(){ arrayListType<int> list;int num;cout << "Line 8: Enter numbers ending with -999" << endl;cin >> num; while (num != -999){list.insert(num);cin >> num;} cout << "Line 15: The list before sorting:" << endl;list.print();cout << endl; list.selectionSort();cout << "Line 19: The list after sorting:" << endl;list.print();cout << endl; return 0;} Header File (arrayList.h) Including images #include <iostream>#include <cassert>...

Q1. Implement a SnapshotArray that supports the following interface: SnapshotArray(int length) initializes an array-like data structure with the given length. Initially, each element equals 0. void set(index, val) sets the element at the given index to be equal to val. int snap() takes a snapshot of the array and returns the snap_id: the total number of times we called snap() minus 1. int get(index, snap_id) returns the value at the given index, at the time we took the snapshot with the given snap_id Example 1: Input: ["SnapshotArray","set","snap","set","get"] [[3],[0,5],[],[0,6],[0,0]] Output: [null,null,0,null,5] Explanation: SnapshotArray snapshotArr = new SnapshotArray(3); // set the length to be 3 snapshotArr.set(0,5); // Set array[0] = 5 snapshotArr.snap(); // Take a snapshot, return snap_id = 0 snapshotArr.set(0,6); snapshotArr.get(0,0); // Get the value of array[0] with snap_id = 0, return 5..

In java Define and create a 2-dimensional array of integers with 4 rows and 8 columns. Print the elements of the array in table format (rows and columns). Replace the element in the second row and third column of the array with the value 99.

What do you think are the most significant benefits of arrays? This is the maximum number of dimensions that an array can have. The difference between a structure and an ordinary variable type is as follows: Use an intricate data structure to demonstrate its use.

JAVA Programming Write a function that returns true if you can partition an array into one element and the rest, such that this element is equal to the product of all other elements excluding itself. Examples canPartition ([2, 8, 4, 1]) → true // 8 = 2 x 4 x 1 canPartition ([-1, -10, 1, -2, 20]) → false canPartition ([-1, -20, 5, -1, -2, 2]) true
