Write a method named lastIndexOf that accepts an array of integers and an * integer value as its parameters and returns the last
evablogger [386]

Answer:

The method is as follows:

public static int lastIndexOf(int [] numbers, int num){

    int lastIndex = numbers[0];

    for(int i =0; i<numbers.length;i+=num){

        lastIndex = numbers[i];

    }

    return lastIndex;

}

Explanation:

This defines the method

public static int lastIndexOf(int [] numbers, int num){

This initializes the lastIndex to the first element of the array

    int lastIndex = numbers[0];

This iterates through every "num" element of the array

    for(int i =0; i<numbers.length;i+=num){

This gets the current index... until the last

        lastIndex = numbers[i];     }

This returns the last

    return lastIndex; }

1. Create an array of ints with 20 elements. With a random number generator, seeded with time, assign a random number between 1
nikdorinn [45]

Answer:

#include <iostream>

#include<time.h>

using namespace std;

void sort(int a[20],int n)   //selection sort

{

   int i,j,temp;

   for(i=0;i<n;i++)        

   {

       for(j=i+1;j<n;j++)  //finds minimum element

       {

           if(a[i]>a[j])     //swaps minimum element to its right place

           {

               temp=a[i];

               a[i]=a[j];

               a[j]=temp;

           }

       }

   }

}

int main()

{

   srand(time(NULL));

   int arr[20],n=20,i;

   for(i=0;i<n;i++)

       arr[i]=rand() % 100 + 1;    //assigns random number to each array element

   cout<<"Before sorting\n";

   for(i=0;i<n;i++)

       cout<<arr[i]<<" ";   //prints array before calling sort func

   sort(arr,20);     //sort the passed array

   cout<<"\nAfter sorting\n";

   for(i=0;i<n;i++)

       cout<<arr[i]<<" ";  //prints array after sorting

   return 0;

}

OUTPUT :

Please find the attachment below.

Explanation:

The program above first assigns random number from 1 to 100 to each element of array using rand(). srand(time(NULL)) is used to generate new number every time otherwise same random number will be produced at a time. Then sorting method is called in which selection sort algorithm is used.

Selection sort algorithm finds the minimum element in each pass and place it into its right position. For example - 34,54,12,5 is passed

After Pass 1 - 5  54  12  34

After Pass 2 - 5  12  54  34

After Pass 3 -  5  12  34  54

The association between a UCS and a CS can be extended to include more stimuli (more stimuli related to the CS can elicit the CR
almond37 [142]

Answer:

The answer is Stimulus generalization

Explanation:

Stimulus generalization is an example of classical condition. Classical conditioning takes a stimulus that does not cause a particular response (neutral stimulus) and then pairs it repeatedly with an unconditioned stimulus that will cause an unconditioned response. In the case of Stimulus generalization, I will give an example of a subject presenting food to a dog once they ring a bell. Lets say that you have taught a dog to salivate every time it hears a bell ring. If you took another bell that has a similar sound and rang it, the dog would still salivate and come pick its food. This is a perfect example of Stimulus generalization. The dog has responded to a new stimulus as if it was the initial conditioned stimulus.

You are working with a database table that contains data about music. The table includes columns for track_id, track_name (name
german

The statement that completes the query is: bytes / 1000 AS kilobytes

<h3>SQL (Structured Query Language)</h3>

This is the language that is used to retrieve, update, and store data in the database.

<h3>Columns</h3>

From the question, we have the following table columns

  • track_id
  • track_name (name of the music track)
  • composer
  • bytes (digital storage size of the music track

To retrieve data from the bytes column, we make use of:

SELECT bytes ......

From the question, we understand that this column should be divided by 1000, and the AS command should be used.

So, the query becomes

SELECT bytes / 1000 AS kilobytes .....

Hence, the statement that completes the query is: bytes / 1000 AS kilobytes
