A query in a database is a request for information stored within a database management system (DBMS), which is the software program that maintains data.

SQL(Structured Query Language ( is a standard language for storing, manipulating, and retrieving data in database.

Five types of SQL queries are:

1) Data Definition Language (DDL).

used to define and modify the structure of a database.

2) Data Manipulation Language (DML).

used to manipulate (change) the data in the database.

3) Data Control Language(DCL).

used for access control and permission management for users in the database.

4) Transaction Control Language(TCL).

used for maintaining consistency of the database and for the management of transactions made by the DML commands.

5) Data Query Language (DQL).

given an array of integers a, your task is to count the number of pairs i and j (where 0 ≤ i < j < a.length), such that a[

Nimfa-mama [501]

Using the knowledge of computational language in C++ it is possible to write a code that given an array of integers a, your task is to count the number of pairs i and j.

<h3>Writting the code:</h3>

// C++ program for the above approach

#include <bits/stdc++.h>

using namespace std;

// Function to find the count required pairs

void getPairs(int arr[], int N, int K)

{

// Stores count of pairs

int count = 0;

// Traverse the array

for (int i = 0; i < N; i++) {

for (int j = i + 1; j < N; j++) {

// Check if the condition

// is satisfied or not

if (arr[i] > K * arr[j])

count++;

}

cout << count;

}

// Driver Code

int main()

{

int arr[] = { 5, 6, 2, 5 };

int N = sizeof(arr) / sizeof(arr[0]);

int K = 2;

// Function Call

getPairs(arr, N, K);

return 0;

}

Write a class called MagicSquare, which contains a single method called check that accepts a two-dimensional array as an argumen

ira [324]

Answer:

public class MagicSquare {

public static void main(String[] args) {

int[][] square = {

{ 8, 11, 14, 1},

{13, 2, 7,12},

{ 3, 16, 9, 6},

{10, 5, 4, 15}

};

System.out.printf("The square %s a magic square. %n",

(isMagicSquare(square) ? "is" : "is not"));

}

public static boolean isMagicSquare(int[][] square) {

if(square.length != square[0].length) {

return false;

}

int sum = 0;

for(int i = 0; i < square[0].length; ++i) {

sum += square[0][i];

}

int d1 = 0, d2 = 0;

for(int i = 0; i < square.length; ++i) {

int row_sum = 0;

int col_sum = 0;

for(int j = 0; j < square[0].length; ++j) {

if(i == j) {

d1 += square[i][j];

}

if(j == square.length-i-1) {

d2 += square[i][j];

}

row_sum += square[i][j];

col_sum += square[j][i];

}

if(row_sum != sum || col_sum != sum) {

return false;

}

return d1 == sum && d2 == sum;
