Issue: Missing Sorting Order in "Coding Practice for Beginners" Section

Description

The links listed under the Coding practice for beginners section are not sorted alphabetically.
According to the project's Contributing Guidelines, new links should be added in alphabetical order.
However, the existing section doesn’t follow this rule, which can make it harder to maintain consistency and quickly find sites.

Suggested Solution

Sort all existing links in the Coding practice for beginners section alphabetically by site name.
This will make the list easier to navigate and keep future contributions organized.

Steps to Reproduce

1. Open the README.md file.
2. Scroll to the Coding practice for beginners section.
3. Observe that the links are not listed in alphabetical order.

Expected Behavior

The links in that section should appear alphabetically to match the contributing rules.

Additional Context

Once this issue is approved, I can submit a PR to reorder the links alphabetically.
