Words having a predefined meaning in a high-level language are known as ______ or reserved words. a. mnemonics b. pseudonyms c. keywords d. semantics.
Words having a predefined meaning in a high-level language are known as keywords or reserved words. Thus, the correct option is :
(c) keywords
Keywords or reserved words are terms in a programming language that have a specific, predefined meaning and cannot be used for other purposes, such as variable names or function names.
For example, in the programming language Python, some keywords include "if," "else," "for," "while," "def," and "return." These words have predefined meanings and are used to define conditional statements, loops, function definitions, and other language-specific constructs.
Using a keyword as a variable name or identifier would lead to a syntax error because it conflicts with the predefined meaning of that word within the language. Therefore, it is important to avoid using keywords as variable names in order to maintain the intended functionality of the programming language.
Therefore, the correct option is : (c) keywords

The given code is a Java program that includes a class called MyDeckSort and another class called MyDeck.
The MyDeckSort class is responsible for sorting a deck of cards using specific operations allowed on the deck, such as looking at the values of the top two cards, exchanging the top two cards, and moving the top card to the bottom of the deck.
The sort method in the MyDeckSort class is where you need to implement the sorting algorithm using the provided operations. Currently, the sort method is empty (marked with // TODO), and you need to write the sorting algorithm there.
The countops method is used to measure the number of operations performed during the sorting process. It also prints the intermediate results if the print variable is set to true.
The main method in the MyDeckSort class is the entry point of the program. It first initializes a deck d with a size of 10 and calls the countops method to perform the sorting and measure the operations. Then, it performs a doubling test by increasing the deck size (N) by a factor of 2 and repeating the sorting process. The number of operations, the ratio of operations compared to the previous deck size, and the elapsed time for each sorting iteration are printed.
The MyDeck class is a separate class that represents a deck of cards. It provides methods to perform operations on the deck, such as checking if the top card is greater than the next, swapping the top two cards, moving the top card to the bottom, and checking if the deck is sorted. It also keeps track of the number of operations performed (ops) and provides methods to retrieve the number of operations and the deck size.
To complete the code, you need to implement the sorting algorithm inside the sort method of the MyDeckSort class using only the provided operations in the MyDeck class. You can use the d.size(), d.moveTopToBottom(), d.topGreaterThanNext(), and d.swapTopTwo() methods to manipulate the deck and perform the sorting.

A positive integer is called a perfect number if it is equal to the sum of all of its positive divisors, excluding itself. For example, 6 is the first perfect number because 6 = 3 + 2 + 1. The next is 28 = 14 + 7 + 4 + 2 + 1. There are four perfect numbers less than 10,000. Write a program to find all these four numbers.
i = 1
while i < 10001:
total = 0
x = 1
while x < i:
if i % x == 0:
total += x
x+=1
if total == i:
print(str(i)+" is a perfect number")
i += 1
When you run this code, you'll see that 6, 28, 496, and 8128 are all perfect numbers.

Classification techniques include support vector machines, naive bayes classifiers, and logistic regression. The k-means clustering algorithm, the Gaussian (EM) clustering algorithm, and others are instances of clustering.
Two methods of pattern recognition used in machine learning are classification and clustering. Although there are some parallels between the two processes, clustering discovers similarities between things and groups them according to those features that set them apart from other groups of objects, whereas classification employs predetermined classes to which objects are assigned. "Clusters" are the name for these collections.

Difference between Oracle And MySQL.
Thank You:)
Answer:
In Explanation
Explanation:
Oracle and MySQL are two relational database management systems (RDBMS) that serve different needs.
Here are some differences between Oracle and MySQL:
Cost: Oracle is a commercial database management system and is expensive, while MySQL is an open-source database management system and is free.
Scalability: Oracle is designed to handle very large amounts of data and can handle more complex tasks than MySQL, making it a better choice for enterprise-level applications. MySQL, on the other hand, is more suitable for small to medium-sized applications.
Features: Oracle has a more extensive feature set than MySQL, including more advanced security, clustering, and partitioning features. MySQL, however, has a simpler feature set and is easier to use.
Performance: Oracle's performance is generally better than MySQL's because it is optimized for handling large amounts of data and complex tasks. However, MySQL's performance can be improved by using caching, indexing, and other optimization techniques.
Licensing: Oracle is proprietary software, and its license is expensive. MySQL is open-source and free to use, which makes it a better choice for developers who want to use free and open-source software.
In summary, Oracle is a better choice for large-scale, complex applications that require advanced security, clustering, and partitioning features, while MySQL is a better choice for small to medium-sized applications that require a simpler feature set and are looking for a free and open-source software solution.
