Answer 2

Can letters be swapped within a string?

Yes, it is possible to swap letters within a string in various programming languages. Different methods can be used to achieve this. For example, in Python, you can use different approaches to achieve this:

1. Using list comprehension: - You can swap letters within a string using list comprehension and the `isalpha()` method to filter out non-alphabetic characters. Here's an example: ``` def sanitize(text): return [ch.lower() for ch in text if ch.isalpha()] ```

2. Using generator function: - Another approach is to use a generator function to yield the lowercase alphabetic characters. Here's an example: ``` def sanitize(text): yield from (ch.lower() for ch in text.lower() if ch.isalpha()) ```

3. Using lambda function and map/filter: - You can also use a lambda function with the `map` and `filter` functions to achieve the same result. Here's an example: ``` sanitize = lambda t: map(str.lower, filter(str.isalpha, text)) ```

In other programming languages, similar operations can be performed using different syntax and methods.

Conclusion

Swapping letters within a string is a common operation in programming and can be achieved using various methods in different programming languages.
