Pyramid Printer 🔺

Final boss. 👑

That's pyramid(4). Look very closely at row 3 of 4: it has 2 spaces in front and 5 stars. Row 4 has 1 space... no wait, 0 spaces and 7 stars.

See the pattern? For a pyramid of n rows, on row i:

• spaces in front = n - i
• stars = i * 2 - 1

Check it: row 1 of 4 ➜ 3 spaces, 1 star. Row 4 of 4 ➜ 0 spaces, 7 stars. It works! 🎯

Build the line with repetition and glue it together:

line = " " * 3 + "*" * 1
print(line)

Your mission

Write a function called pyramid(n) that prints an n-row star pyramid, centred with spaces.

This one prints instead of returning — I'll call pyramid(4) and pyramid(3) and count your stars and spaces. Make it work for any n, not just one. 🏗️
