Expected Output

When this program is compiled and executed, the terminal outputs:

Leaderboard (Sorted by Score):
1. Charlie    : 99 pts
2. Alice      : 95 pts
3. Diana      : 88 pts
4. Bob        : 82 pts

How the Code Works

In Lua, tables serve as arrays, dictionaries, and objects. table.sort sorts array elements in-place using a comparator function. ipairs iterates indexed integer tables in sequential order.

Time Complexity

O(N log N)

Space Complexity

O(1) auxiliary

Key Takeaways & Best Practices

table.sort modifies tables in-place.
ipairs iterates array-like numeric keys sequentially.
