Viruses spread when the software or documents they get attached to are transferred from one computer to another using a network, a disk, file sharing methods, or through infected e-mail attachments. Some viruses use different stealth strategies to avoid their detection from anti-virus software.
Answer:
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).
used for performing queries on the data within schema objects.
Answer:
Starting from root, recursively traverse the min-heap. Once we find a key with value less than our X, we know that every key in subtree of that key will be also smaller than our X. Otherwise, we should keep traversing.
Explanation:
The complexity of this algorithm will be O(N) where N is the number of keys in our min-heap.
That IP address is either Internal, private or reserved
