Using JavaScript, how does a web page react when the user enters a wrong email ID in a registration form?

Write at least and explain four types of escape sequences and create an example in an IDE which consist of the mentioned escape

slamgirl [31]

Answer:

- \' is used to escape a single quote in a string enclosed in single quotes like;

my_string = 'this is John\'s ball'.

- \n is used to jump to a new line, Eg;

my_string = "Johns is a good boy\nbut he hates going to school."

the next set of the string after the '\n' character is displayed on the next line.

- \t is used to add a tab space to a string.

my_string = 'Jane is \thungry'

the character adds four character spaces before the word 'hungry'.

- \r adds a carriage return (or enter in keyboards) to start a new block paragraph in a string.

my_string = "Johns is a good boy\rbut he hates going to school."

Explanation:

Escape sequences in programming are used to format strings or output syntax of a program. They always begin with the backslash. Examples of escape sequence are " \' ", "\n", "\t", "\r", etc.

Dropbox and Microsoft's OneDrive are both popular applications for storing files. What is a fundamental difference between Dropb

Paha777 [63]

The difference is that Dropbox offers just 2 GB free storage space while Microsoft's OneDrive gives 5 GB in terms of free storage space.

<h3>What is Microsoft OneDrive?</h3>

This is known to be a file hosting software and it also does synchronization service given by Microsoft.

Some other fundamental difference between Dropbox and OneDrive in terms of Business is that Dropbox is known to often give unlimited storage for about $20 to paid user/month while OneDrive is said to only give unlimited storage for $10 per paid user/month.

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.
