Twitter

Given an app.js file and a database file twitterClone.db consisting of five tables user, follower, tweet, reply, and like.

Write APIs to perform operations on the tables user, follower, tweet, reply, and like containing the following columns,

User Table

Column Type

user_id INTEGER

name TEXT

username TEXT

password TEXT

gender TEXT

Follower Table

Column Type

follower_id INTEGER

follower_user_id INTEGER

following_user_id INTEGER

Here, if user1 follows user2 then,

follower_user_id is the user ID of user1 and following_user_id is the user ID of user2.

Column Type

tweet_id INTEGER

tweet TEXT

user_id INTEGER

date_time DATETIME

Reply Table

Column Type

reply_id INTEGER

tweet_id INTEGER

reply TEXT

user_id INTEGER

date_time DATETIME

Like Table

Column Type

like_id INTEGER

tweet_id INTEGER

user_id INTEGER

date_time DATETIME

For this question

Add two polynomials

Given two polynomials A and B, write a program that adds the given two polynomials A and B.

if the in puts are

4

0 5

1 0

2 10

3 6

4

0 -5

1 0

2 -10

3 -6

then the result is 0 but it is not showing the result from the code of Question #175894

Experiment with the C/C++ implementations of the various sorting and searching algorithms in a

single program with time complexity:

 Bubble sort

 Insertion sort

 Radix sort

 Linear search

 Binary search

Considering the following functions have been made

1)void Print_Reverse_List(List* node)

2)void Insert_Element(List** head, int data)

3)void PrinList(List* node)

4)void search_Element(List *node, int x)

5)int Length(List *node)

Your task is to create the following functions for the given code:

1)Insert_Element_at(int x)

2)bool is_Empty()

3)bool Delete_Element(int x)

4)void Empty_List()

5)void Copy_List(...)

make menu for the five functions

class List{

public:

int item;

int pos;

List* nextNode

};

List* linkList=NULL;

int ch=-1;

int number;

int position;

while(ch!=6){

cout<<"1. Insert Element\n";

cout<<"2. Print List\n";

cout<<"3. Search Element\n";

cout<<"4. Display Length of List\n";

cout<<"5. Print Reverse List\n";

cout<<"6. Exit\n";

cout<<"Your choice: ";

cin>>ch;

cout<<"\n";

switch(ch){

case 1:

}

Convert the expression into postfix notation and then verify if it is correct or not,direct answers for both 5conversion are not allowed for verification take dummy values for eachvariable.

a+b*(c/d-e)%(f+g*h)-i

what will be the output of the following code? Rough work must be done as well.

int[] values={1,3,5,7,9,11,13,15,17,19};

    Stack s=new Stack();

    for(int i=0;i<values.length;i++)

    {

        s.push(values[i]);

    }

    int n=25;

    for(int i=0;i<4;i++)

    {

        n+=s.pop();

    }

    for(int i=0;i<2;i++)

    {

        n-=s.pop();

    }

    cout<<"\n"<<endl;
