代码块美化测试

这是一个内联代码测试：const x = 123，看看效果如何。

JavaScript 示例

// JavaScript 代码示例
function fibonacci(n) {
    if (n <= 1) return n;
    return fibonacci(n - 1) + fibonacci(n - 2);
}

const result = fibonacci(10);
console.log(`Fibonacci(10) = ${result}`);

Python 示例

# Python 代码示例
def quicksort(arr):
    if len(arr) <= 1:
        return arr
    pivot = arr[len(arr) // 2]
    left = [x for x in arr if x  pivot]
    return quicksort(left) + middle + quicksort(right)

print(quicksort([3, 6, 8, 10, 1, 2, 1]))

PHP 示例

<?php
// PHP 代码示例
class Calculator {
    public function add(int $a, int $b): int {
        return $a + $b;
    }
}

$calc = new Calculator();
echo $calc->add(5, 3); // 输出: 8

Bash 示例

#!/bin/bash
# Bash 脚本示例
for i in {1..5}; do
    echo "Iteration $i"
    sleep 1
done

echo "Done!"

SQL 示例

-- SQL 查询示例
SELECT 
    users.name,
    COUNT(orders.id) AS order_count,
    SUM(orders.total) AS total_spent
FROM users
LEFT JOIN orders ON users.id = orders.user_id
WHERE users.created_at > '2024-01-01'
GROUP BY users.id
HAVING total_spent > 1000
ORDER BY total_spent DESC
LIMIT 10;

测试完成！如果代码块有语法高亮、行号、复制按钮，说明集成成功 ✅
