Python String and Armstrong Number

Neudesic data-processing utilities often receive text alongside numeric configuration values. Implement one function that normalizes a text value and finds all Armstrong numbers within a specified range.

Your function must:

1. Convert alphabetic characters to lowercase.
2. Replace every non-alphanumeric character with a space.
3. Collapse consecutive whitespace and remove leading or trailing whitespace.
4. Reverse the order of the resulting words, without reversing characters within each word.
5. Return every Armstrong number from 0 through limit, inclusive. A number is an Armstrong number when it equals the sum of each digit raised to the number of digits in the number.

Formal Specification

Input consists of an ASCII string text and a non-negative integer limit. Return a dictionary with two keys: transformed, a string, and armstrong_numbers, a list of integers in ascending order.

Examples

Example 1

Input: text = " Neudesic, Azure Team! ", limit = 500

Output: {"transformed": "team azure neudesic", "armstrong_numbers": [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 153, 370, 371, 407]}

Punctuation becomes spaces, words are normalized, and their order is reversed.

Example 2

Input: text = "Python## Algorithms", limit = 10

Output: {"transformed": "algorithms python", "armstrong_numbers": [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]}

Constraints

• 0 <= len(text) <= 10^5
• 0 <= limit <= 10^6
• text contains ASCII characters only.
• Armstrong numbers must be returned in ascending order.
