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.

205 6

406 7

5205 9

This is the formula for the future worth of an investment over time with consistent additional monthly payments and a steady rat

stepladder [879]

Answer:

The code is given in C++ below

Explanation:

#include <iostream>

using namespace std;

int main()

{

float fv,pv,r,k,n,pmt,totalmoneyinvested;

pv=1000.00;

r=6/100;

k=12; //The value of k should be 12 for monthly installments

n=45;

pmt=250;

totalmoneyinvested=pv+(pmt*12*45); //The total money you invested

fv=pv*(1+r/k)*n*k+pmt*((1+r/k)*n*k-1)*(1+r/k)*r/k;

cout<<"Initial Investment:"<<" $"<<pv;

cout<<"\nRate Of Return:6%";

cout<<"\nLength of Time:"<<n<<"year";

cout<<"\nMonthly Payment:"<<" $"<<pmt;

cout<<"\nFinal Amount:"<<" $"<<fv;

cout<<"\nThe Money You Invested Is $"<<totalmoneyinvested<<" And The Final Amount Is $"<<fv;

return 0;

By arranging users into security groups, it is possible to set permissions at a group-level, avoiding the unwieldy alternative o

Anni [7]

Answer:

The department by department is arranging users into security groups to set permission at a group-level.

Explanation:

Team by team is just formed group method but the team been set will work on based on the project. Once the project is getting over then the team group assigned permission has to be disabled or deleted.

Department by department is just good methods where each department will have a list of users and easy to assign the group.

user-by-user. is just assigning the rights of each individual user. But if the user has multiple departments login it will be good advice.

organization-by-organization. It is just assigning rights to complete users list in the organization.

Phone cords are a type of twisted-pair cable and use an rj-45 connector.

Nezavi [6.7K]

The answer is FALSE

The RJ11 is most commonly known as the "telephone" standard. Most wired landline phones almost certainly use an RJ11 jack or an RJ11 connector. RJ11 has between 4 or 6 wire connection, but only 2 wires are used for connection as compared to a RJ14 which is also used in connecting telephone lines and uses 4 wires for connection.
