Fixed asteroid collision logic & added dynamic user input support

[Shrinidhibijapur]

Summary

Improved the asteroid collision program by fixing minor logic issues and enhancing interactivity.

Changes Made

• Fixed logical errors in collision handling (equal-size and chain collisions).
• Added user input using loops for dynamic asteroid array entry.
• Improved output formatting to clearly show final asteroid states.
• Cleaned up code structure for readability.

Benefits

• Now handles all edge cases correctly.
• Accepts any size of input dynamically from the user.
• Easier to test multiple scenarios interactively.

Example

Input
5
5 10 -5 8 -8

Output
After collisions: 5 10
