The ciphers that are considered secure, such as RSA and ECDHE, the Vernam cipher is the only one that is truly unbreakable when used properly.

The Vernam cipher, also known as the one-time pad, is considered unbreakable when used properly. This is because it uses a randomly generated key that is the same length as the message being encrypted, and this key is only used once. This means that even with the most advanced computing power, it would be impossible to crack the cipher without knowing the key.

The Vernam cipher works by XORing (exclusive or) each bit of the plaintext message with a corresponding bit of the key. This produces a ciphertext that appears random and is indecipherable without the key. As long as the key is kept secret and only used once, the cipher is unbreakable.

When using the procedural interface of mysqli, you perform database operations by interacting with the MySQL server through a series of functions provided by the mysqli extension. The procedural interface is an alternative to the object-oriented interface and offers a more straightforward approach to performing tasks, particularly for those who are new to PHP and database programming.

To begin, you establish a connection to the MySQL server by calling the mysqli_connect() function. This function requires the server hostname, username, password, and database name as its parameters. If the connection is successful, it returns a mysqli object that you use for subsequent database operations.

Next, you can perform various database operations, such as querying data, inserting records, updating records, or deleting records, by using mysqli functions that interact with the mysqli object created earlier. For example, to execute a SELECT query, you can use the mysqli_query() function, passing the connection object and the SQL query as parameters. This function returns a result set that you can then process using other mysqli functions, like mysqli_fetch_assoc() or mysqli_fetch_array().

To insert, update, or delete records, you can use the same mysqli_query() function, but with different SQL queries. For instance, to insert a new record, you would use an INSERT statement in the SQL query parameter.

Error handling is crucial when working with databases, and the procedural interface of mysqli provides several functions to check for and handle errors, such as mysqli_connect_error(), mysqli_connect_errno(), and mysqli_error().

Finally, after completing all database operations, it's essential to close the connection using the mysqli_close() function, which takes the mysqli object as its parameter.

In summary, the procedural interface of mysqli allows you to perform database operations in PHP by using a series of functions that interact with the MySQL server. This approach is straightforward and especially useful for those new to PHP and database programming.

Arrays are more efficient for accessing elements by index, while ArrayLists are more efficient for adding or removing elements.

In Java, an array is a fixed-size collection of elements of the same data type that is declared with a specific length at the time of creation. Once an array is created, its size cannot be changed, and elements can be accessed using their index position.

On the other hand, an ArrayList is a dynamic collection of objects that can grow or shrink as needed. It is part of the Java Collections Framework and provides methods for adding, removing, and manipulating elements. Unlike arrays, ArrayLists can hold objects of different types and do not require a fixed size at the time of creation.

In summary, the main differences between an array and an ArrayList in Java are:

- Arrays have a fixed size while ArrayLists can grow or shrink dynamically.

- Arrays can only hold elements of the same data type while ArrayLists can hold objects of different types.

- Arrays are more efficient for accessing elements by index, while ArrayLists are more efficient for adding or removing elements.

Agile teams determine the size of a story through a process called relative estimation. This involves breaking down the story into smaller, more manageable tasks or sub-tasks and then assigning a number of story points to each of these tasks based on their complexity, the effort required, and the level of uncertainty involved. The sum of these story points then gives an estimate of the overall size of the story.

Agile teams determine the size of a story by using story points, a common unit of measure. The process typically involves the following steps:

1. Team members familiarize themselves with a baseline story that represents a known level of effort and complexity. This baseline story is assigned a specific story point value, often using a scale such as the Fibonacci sequence (e.g., 1, 2, 3, 5, 8, 13).

2. The team discusses each new user story, comparing its effort and complexity to the baseline story. They consider factors like the scope of work, potential risks, and any dependencies or unknowns.

3. Team members assign story points to the new user story based on their consensus of its relative size compared to the baseline story. For example, if they believe the new story requires twice the effort of the baseline story, they might assign it twice the story points.

4. The team continues to refine their estimates as they gain more knowledge about the project and its requirements.

5. Over time, the team's velocity (the total number of story points completed per iteration) can be used to help predict the amount of work they can accomplish in future iterations.

Using story points as a measure for story sizes helps Agile teams to focus on the relative effort and complexity of tasks, rather than attempting to estimate the exact time required for each story.
