Update sol1.py

[Subhan030]

The main change made to your code was the range for numbers being checked. Your code checks numbers from 1000 to 999999, while the adjusted code checks from 10 up to 354294. This new range is based on the mathematical upper bound for this problem, since 6 * 9^5 = 354294, and any number beyond this can't be written as the sum of the fifth powers of its digits.

Approach: Both codes use the same logic, leveraging a precomputed dictionary and a helper function, so the core approach is identical.
Reason for range adjustment: The range was mathematically justified to be minimal and correct, removing unnecessary computations for numbers that cannot possibly fit the required property.

Describe your change:

• Add an algorithm?
• Fix a bug or typo in an existing algorithm?
• Add or change doctests? -- Note: Please avoid changing both code and tests in a single pull request.
• Documentation change?
