     ```
     sudo apt update
     sudo apt upgrade
     ```

4. **Download and Run cPanel Installation Script**:
   - cPanel provides an installation script for Ubuntu systems. Download the script and execute it. Run the following commands:
     ```
     curl -o latest https://securedownloads.cpanel.net/latest
     chmod +x latest
     sudo ./latest
     ```
   - This script will start the cPanel installation process. Follow the on-screen prompts to complete the installation.

Understanding the fundamental commands of SQL (Structured Query Language) is crucial for mastering database management and querying. In this article, we'll explore the essential SQL commands that every developer should know to navigate and manipulate data effectively.

### 1. SELECT Statement:
The SELECT statement is the backbone of SQL, allowing you to retrieve data from a database. You can specify the columns you want to retrieve, the tables to query, and apply conditions to filter the results.

```sql
SELECT column1, column2
FROM table_name
WHERE condition;
```

### 2. INSERT Statement:
The INSERT statement is used to add new records to a table.

```sql
INSERT INTO table_name (column1, column2)
VALUES (value1, value2);
```

### 3. UPDATE Statement:
The UPDATE statement modifies existing records in a table.

```sql
UPDATE table_name
SET column1 = value1, column2 = value2
WHERE condition;
```

### 4. DELETE Statement:
The DELETE statement removes records from a table based on specified conditions.

```sql
DELETE FROM table_name
WHERE condition;
```

### 5. CREATE TABLE Statement:
The CREATE TABLE statement is used to create a new table in the database.

```sql
CREATE TABLE table_name (
    column1 datatype,
    column2 datatype,
    ...
);
```

### 6. ALTER TABLE Statement:
The ALTER TABLE statement is used to modify an existing table by adding, modifying, or dropping columns.

```sql
ALTER TABLE table_name
ADD column_name datatype;

ALTER TABLE table_name
MODIFY column_name datatype;

ALTER TABLE table_name
DROP COLUMN column_name;
```

### 7. DROP TABLE Statement:
The DROP TABLE statement deletes an existing table along with its data.

```sql
DROP TABLE table_name;
```

### Conclusion:
Mastering these essential SQL commands will provide you with a solid foundation for working with databases. Whether you're a beginner or an experienced developer, understanding these commands is crucial for efficiently managing data and performing complex queries. Keep practicing and exploring SQL to unlock its full potential in your projects.

Remember, while these commands are essential, SQL is a vast language with many advanced features and functions. Continuously learning and experimenting with SQL will help you become a proficient database developer. Happy coding!

Weekly Challenge 258
Tags: perl, python, theweeklychallenge
Published: 2024-03-03 11:05:29

Each week Mohammad S. Anwar sends out [The Weekly Challenge](https://theweeklychallenge.org/), a chance for all of us to come up with solutions to two weekly tasks. My solutions are written in Python first, and then converted to Perl. It's a great way for us all to practice some coding.

[Challenge](https://theweeklychallenge.org/blog/perl-weekly-challenge-258/), [My solutions](https://github.com/manwar/perlweeklychallenge-club/tree/master/challenge-258/sgreen)

## Task 1: Count Even Digits Number

### Task

You are given a array of positive integers, `@ints`.

Write a script to find out how many integers have even number of digits.

### My solution

This is relatively straight forward, and probably doesn't need an explanation for the people reading this post. The only thing worth mentioning is that we need to convert the integer to a string to get its length. The challenge specifically mentions positive integers only, so we don't need to worry about the length of negative numbers not being the number of digits it has.

```python
def count_even_digits(ints: list) -> int:
    return sum(1 for i in ints if len(str(i)) % 2 == 0)
```

Perl on the other hand doesn't care (except in a few rare circumstances) if the value is a string or number. grep in a scalar context will return the number of items that match the criteria.

```perl
sub main (@ints) {
    my $count = grep { length($_) % 2 == 0 } @ints;
    say $count;
}
```

### Examples

```bash
$ ./ch-1.py 10 1 111 24 1000
3

$ ./ch-1.py 111 1 11111
0

$ ./ch-1.py 2 8 1024 256
1
```

## Task 2: Sum of Values

### Task

You are given an array of integers, `@ints` and an integer `$k`.

Write a script to find the sum of values whose index binary representation has exactly `$k` number of bits set.

### My solution

This could also be done in a single line, but the code would be hard to understand. Therefore I took a more straight forward approach and use a `for` loop. For each position, if the number of bits set is `$k` I add that value to the `total` variable.

```python
def sum_of_values(ints: list, k: int) -> int:
    total = 0

    for pos, value in enumerate(ints):
        if k == bin(pos).count('1'):
            total += value

    return total
```

### Examples

```bash
$ ./ch-2.py 2 5 9 11 3 1
17

$ ./ch-2.py 2 5 9 11 3 2
11

$ ./ch-2.py 2 5 9 11 3 0
2
```
