Is there a picture to go along with this? I don’t see one and an willing to help!
Answer:
E
Explanation:
If you follow the line of code and add 1, 2, and then 3, 10 + 1 + 2 + 3 = 16.
Answer:
b. size
Explanation:
We can use the size() method of java.util.ArrayList to determine the size of an ArrayList in Java. The size() method of the ArrayList class returns an integer which is equal to the number of elements present in the ArrayList.
Below is an example code to illustrate the use of the size() method of the ArrayList:-
ArrayList<Integer> aList = new ArrayList<Integer>(5);
aList.add(25);
aList.add(2);
aList.add(5);
aList.add(22);
System.out.println("Size of the array list: " + aList.size());
This will print the size of the array list as 4 since we've added four numbers into the array list.
Answer:
// C++ program to find k largest elements in the array
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variable
int n,k;
cout<<"Enter the number of elements of array:";
// read the value of n
cin>>n;
// declare the array of size n
int arr[n];
cout<<"Enter the elements of array:";
// read the elements of array
for(int a=0;a<n;a++)
{
cin>>arr[a];
}
cout<<"Enter the value of K:";
cin>>k;
// call the function to perform selection Sort
sort(arr, arr+n);
cout << k<<" largest elements of the array are: ";
// print k largest elements of the array
for (int i=n-1; i>n-k-1; i--)
cout << arr[i] << " ";
return 0;
}
Explanation:
Read the number of elements in the array.Then create an array of size "n" and read n elements of the array.Sort the array in ascending array.Then Read the value of k from user.Find the k Elements from the end of the array.This will be the k largest elements of the array.
Output:
Enter the number of elements of array:8
Enter the elements of array:34 8 75 99 12 7 5 55
Enter the value of K:3
3 largest elements of the array are: 99 75 55
