Quantum computing is a type of computing that uses quantum bits, or qubits, which can exist in multiple states at the same time. This allows quantum computers to perform calculations that would take traditional computers a very long time to solve. Quantum computers use principles of quantum mechanics to process information and solve problems, making them incredibly powerful tools for solving complex problems in fields like cryptography, finance, and science. However, quantum computing is still in its early stages and is not yet widely available or understood.

Explain deep learning with simple sentences
Deep learning is a type of artificial intelligence where computers learn to recognize patterns by analyzing large amounts of data. They use complex algorithms and neural networks to understand and interpret information, allowing them to make predictions, solve problems and identify patterns in ways that are similar to the human brain. Deep learning is used in a wide range of applications, including speech recognition, image classification, and natural language processing.
explain find_in_set
The `FIND_IN_SET` function is a MySQL function that searches for a value within a comma-separated list of values. It takes two arguments: the value to search for and the comma-separated list to search within.
The function returns the position of the value within the list if found, or 0 if not found. The position is determined by the order in which the values appear in the list.
Here's an example to illustrate its usage:
```
SELECT FIND_IN_SET('apple', 'apple,banana,grape');
```
In this example, the value 'apple' is searched within the list 'apple,banana,grape'. Since 'apple' is the first value in the list, the function will return 1.
Please note that the `FIND_IN_SET` function is case-sensitive, meaning it treats uppercase and lowercase letters as distinct values.
