How do you add a string the queue?

If you want to add a string to the queue, it depends on how you coded the queue, whether the queue accepts directly a string, or if it accepts an array of characters etc.

Can you check the original code?

write a simple php application that reads variable from the url(as query string)p,t,r and calculate the simple interest(i) if th t and r is less than 25 and 5% pa respectively

To add a string to a queue, follow these steps:

1. First, create a queue data structure to store the elements. Depending on the programming language you are using, the implementation may differ. For example, in Python, you can use the `queue` module, or you can create a custom class.

2. Initialize an empty queue.

3. Use the enqueue operation to add elements to the queue. The enqueue operation is used to insert an element at the rear(end) of the queue. In the case of a string, you would add the string to the end of the queue.

4. To enqueue a string, you can use the appropriate method provided by the queue data structure. This method might be called `enqueue`, `push`, or `add`, depending on the specific implementation or programming language.

For example, in Python, using the `queue` module, you can enqueue a string with the `put` method. Here's an example:

```python
from queue import Queue

# Create an empty queue
queue = Queue()

# Enqueue a string
queue.put("Hello World")
```

Remember, the specific method names and syntax might vary based on the programming language or type of queue implementation you are using.
