When reading the story, you know that the code has been created by humans, so it might actually be english and use concepts like our number system, our computer code system (I'm thinking ASCII), things that you should not assume when decoding a real alien message.

Looking at the numbers I notice that digits 6 to 9 do not occur in the message, which is statistically unexpected. This leads me to believe the number base might be 6 rather than our common base 10. In the story there are insects mentioned. Insects have 6 legs, so this makes sense (after all, our base 10 was based on the number of fingers).

Next, I notice the code 052 appearing regularly, so that could be a space. Let's check a hypothesis. 052 in base 6 is 5*6+2 = 32. 32 is the ASCII code for a space!!

Now, a decoding algorithm is ready to be devised:

"for each number in the sequence, parse it as a base-6 number and then print out its corresponding ASCII value".

The following node.js snippet does this:

var code = ['220','241','255','245','052','313',

           '311','052','312','303','052','312',

           '252','245','052','205','241','251',

           '253','243','052','203','253','302',

           '251','244','303','301','053'];

           

var msg = "";

for (let n of code) {

   msg += String.fromCharCode(parseInt(n,6));

}

console.log(msg);


And the message is.........:

<em>Take us to the Magic Kingdom!</em>

So, do these aliens want to visit Disneyland????

What is key to remember when handling linked lists?
djyliett [7]

Answer:

Some key points to remember, when handling the linked list are as follow:

  • Linked list is the linear data structure in which each of the elements contain separate object.
  • Linked list components are not store in a contiguous location.
  • In the linked list the elements or components are basically use the pointers for linked with another elements.
  • The last node of the linked list must contain null value.
  • In the linked list, the allocation of the memory is equal to upper node limit.

State 3 file formats explain them in an understanding manner apart from Microsoft word and PDF
natita [175]

Answer:

Hope below explanations are enough.

Explanation:

1. JPEG (or JPG) - Joint Photographic Experts Group

JPEGs might be the most common file type you run across on the web, and more than likely the kind of image that is in your company's MS Word version of its letterhead. JPEGs are known for their "lossy" compression, meaning that the quality of the image decreases as the file size decreases.

You can use JPEGs for projects on the web, in Microsoft Office documents, or for projects that require printing at a high resolution. Paying attention to the resolution and file size with JPEGs is essential in order to produce a nice looking project.

2. PNG - Portable Network Graphics

PNGs are amazing for interactive documents such as web pages, but are not suitable for print. While PNGs are "lossless," meaning you can edit them and not lose quality, they are still low resolution.

The reason PNGs are used in most web projects is that you can save your image with more colors on a transparent background. This makes for a much sharper, web-quality image.

3. GIF - Graphics Interchange Format

GIFs are most common in their animated form, which are all the rage on Tumblr pages and in banner ads. It seems like every other day we have a new Grumpy Cat or Honey Boo Boo animated GIF. In their more basic form, GIFs are formed from up to 256 colors in the RGB colorspace. Due to the limited number of colors, the file size is drastically reduced.

This is a common file type for web projects where an image needs to load very quickly, as opposed to one that needs to retain a higher level of quality.

4. TIFF - Tagged Image File

A TIF is a large raster file that doesn't lose quality. This file type is known for using "lossless compression," meaning the original image data is maintained regardless of how often you might copy, re-save, or compress the original file.

Despite TIFF images' ability to recover their quality after manipulation, you should avoid using this file type on the web -- it can take forever to load. TIFF files are also commonly used when saving photographs for print.

5. PSD - Photoshop Document

PSDs are files that are created and saved in Adobe Photoshop, the most popular graphics editing software ever. This type of file contains "layers" that make modifying the image much easier to handle. This is also the program that generates the raster file types mentioned above.

The largest disadvantage to PSDs is that Photoshop works with raster images as opposed to vector images.

I would recommend A. Quickly on the left and move ahead of it because you should always pass on the left and seeing as it is a large truck, you would want to get ahead of it ASAP.

9.10: Reverse ArrayWrite a function that accepts an int array and the array ’s size as arguments . The function should create a
AleksandrR [38]

Answer:

#include <iostream>

using namespace std;

int * reverse(int a[],int n)//function to reverse the array.

{

   int i;

   for(i=0;i<n/2;i++)

   {

       int temp=a[i];

       a[i]=a[n-i-1];

       a[n-i-1]=temp;

   }

   return a;//return pointer to the array.

}

int main() {

   int array[50],* arr,N;//declaring three variables.

   cin>>N;//taking input of size..

   if(N>50||N<0)//if size greater than 50 or less than 0 then terminating the program..

   return 0;

   for(int i=0;i<N;i++)

   {

       cin>>array[i];//prompting array elements..

   }

   arr=reverse(array,N);//function call.

   for(int i=0;i<N;i++)

   cout<<arr[i]<<endl;//printing reversed array..

   cout<<endl;

return 0;

}

Output:-

5

4 5 6 7 8

8

7

6

5

4

Explanation:

I have created a function reverse which reverses the array and returns pointer to an array.I have also considered edge cases where the function terminates if the value of the N(size) is greater than 50 or less than 0.
