A Bean array is defined to be an array where for every value n in the array, there is also an element n-1 or n+1 in the array. For example, {2, 10, 9, 3} is a Bean array because 2 = 3-1 10 = 9+1 3 = 2 + 1 9 = 10 -1 Other Bean arrays include {2, 2, 3, 3, 3}, {1, 1, 1, 2, 1, 1} and {0, -1, 1}. The array {3, 4, 5, 7} is not a Bean array because of the value 7 which requires that the array contains either the value 6 (7-1) or 8 (7+1) but neither of these values are in the array. Write a function named isBean that returns 1 if its array argument is a Bean array. Otherwise it returns a 0. */ package dev; /** * * @author Tej Bist */ public class BeanArray { public static void main(String arg[]) { System.out.println(new BeanArray().isBean(new int[]{3, 4, 5, 7})); } private int isBean(int[] nu) { for (int i = 0; i < nu.length; i++) { int count = 0; for (int j = 0; j < nu.length; j++) {

Simple MailTransfer Protocol (SMTP) SMTP is a simple ASCII protocol for transferring mail between hosts in the TCP/IP suite. After establishing the TCP connection to port 25 , the sending machine, operating as the client, waits for the receiving machine, operating as the server, to talk first. The server starts by sending a line of text giving its identity and telling whether it is prepared to receive mail. If it is not, the client releases the connection and tries again later. If the server is willing to accept email, the client announces whom the email is coming from and whom it is going to. If such a recipient exists at the destination, the server gives the client the go-ahead to send the message. Then the client sends the message and the server acknowledges it. No checksums are needed because TCP provides a reliable byte stream. If there is more email, that is now sent. When all the email has been exchanged in both directions, the con

PL/SQL ( Procedural Language/Structured Query Language ) is Oracle Corporation 's procedural language extension for SQL and the Oracle relational database . PL/SQL is available in Oracle Database TimesTen in-memory database and IBM DB2 . Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops . It allows declaration of constants and variables , procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation . One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmati
