Answer:

The if statement is used to check a condition and if the condition is true, we run a block of statements (called the if-block), else we process another block of statements (called the else-block). The else clause is optional.

Answer:

You'd use an if statement if something happens. What I mean is that {If this happens} Then that happens but if the if doesnt happen then the then doesnt happen

Answer:

Content delivery network.

Explanation:

The content delivery network is also known as a network of content distribution it is a globally decentralized network of the proxy servers and the server farms.The main aim of a content delivery network is to giving the insularity of the high accessibility and efficiency by distributing the service to the end-user.

The content delivery network is a type of hardware and software network that stores u data in different geographical locations also giving the data available on the request.

Show the array that results from the following sequence of key insertions using a hashing system under the given conditions: 5,

sergejj [24]

Answer:

a) Linear probing is one of the hashing technique in which we insert values into the hash table indexes based on hash value.

Hash value of key can be calculated as :

H(key) = key % size ;

Here H(key) is the index where the value of key is stored in hash table.

----------

Given,

Keys to be inserted are : 5 , 205, 406,5205, 8205 ,307

and size of the array : 100.

First key to be inserted is : 5

So, H(5) = 5%100 = 5,

So, key 5 is inserted at 5th index of hash table.

-----

Next key to inserted is : 205

So, H(205) = 205%100 = 5 (here collision happens)

Recompute hash value as follows:

H(key) =(key+i) % size here i= 1,2,3...

So, H(205) =( 205+1)%100 = 206%100 = 6

So, key 205 is inserted in the 6th index of the hash table.

----------

Next Key to be inserted : 406

H(406) = 406%100 = 6(collision occurs)

H(406) =(406+1) %100 = 407%100 = 7

So, the value 406 is inserted in 7the index of the hash table.

-----------------

Next key : 5205

H(5205) = 5205%100 = 5(collision)

So, H(5205) = (5205+1)%100 = 6( again collision)

So, H(5205) = 5205+2)%100 = 7(again collision)

So, H(5205) = (5205+3)%100 = 8 ( no collision)

So, value 5205 is inserted at 8th index of the hash table.

-------------

Similarly 8205 is inserted at 9th index of the hash table because , we have collisions from 5th to 8th indexes.

-------------

Next key value is : 307

H(307) = 307%100 = 7(collision)

So, (307+3)%100 = 310%100 = 10(no collision)

So, 307 is inserted at 10th index of the hash table.

So, hash table will look like this:

Key index

5 5

205 6

406 7

5205 8

8205 9

307 10

b) Quadratic probing:

Quadratic probing is also similar to linear probing but the difference is in collision resolution. In linear probing in case of collision we use : H(key) = (key+i)%size but here we use H(key) =( key+i^2)%size.

Applying Quadratic probing on above keys:.

First key to be inserted : 5.

5 will go to index 5 of the hash table.

-------

Next key = 205 .

H(205) = 205%100 = 5(collision)

So. H(key)= (205+1^2)%100 = 6(no collision)

So, 205 is inserted into 6th index of the hash table.

--------

Next key to be inserted 406:

So, 406 %100 = 6 (collision)

(406+1^2)%100 = 7(no collision)

So, 406 is moved to 7th index of the hash table.

----------

Next key is : 5205

So, 5205%100 = 5 (collision)

So, (5205+1^2)%100 = 6 ( again collision)

So, (5205+2^2)%100 = 9 ( no collision)

So, 5205 inserted into 9th index of hash table.

-----------

Next key is 8205:

Here collision happens at 5the , 6the , 9th indexes,

So H(8205) = (8205+4^2)%100 = 8221%100 = 21

So, value 8205 is inserted in 21st index of hash table.

--------

Next value is 307.

Here there is collision at 7the index.

So, H(307) = (307+1^2)%100 = 308%100= 8.

So, 307 is inserted at 8the index of the hash table.

Key Index

5 5

205 6

406 7

5205 9

8205 21

307 8

What are the two major types of sas steps?

QveST [7]

The two major SAS steps are data and proc.

SAS programming structure is based on two essential steps, Data and Proc.

1. The DATA step:

This involves collecting and uploading the essential data to the program memory. It is used to update, modify and edit the data in case of any errors once it has been added to a dataset. New datasets can be created from existing ones by updating, editing, and/or merging them. at the end of this step, SAS data sets are created.

2. The PROC step:

This step processes and analyses the data collected into datasets in the previous step. it is used to perform specific functions on the data. at the end of the proc step, a result or report is produced.

In a SAS code, each line of code should begin either with a DATA or PROC step.

<u>While the other options are incorrect because: </u>

<u />

Analysis: analysis is done in the PROC step.
Content: Data or content is collected in the DATA step.
Stat: a stat function acquires the status information regarding a specific file. Functions are performed on the datasets in the PROC step.
Run: This command is used to execute a code.
Import: Datasets are created by importing data from other datasets and outside.
Print: the report produced at the end of the PROC step can be printed as a hard copy.
