Part 2 - Exercise 3 Solution

-- Problem: Imagine a game where a player starts at level 1 and gains
-- a level when they gain 10 times their current level in experience.
-- Given a player's total experience, calculate what level they are.
-- Hard mode: do this without using a while-do or repeat-until block.
-- Input
total_xp = 270
level = 1
-- Calculation
while total_xp >= level * 10 do
    total_xp = total_xp - level * 10
    level = level + 1
end
-- Output
print("Level:", level)

-- Alternate solution using a repeat-until
total_xp = 270
level = 0
repeat
    level = level + 1
    total_xp = total_xp - level * 10
until total_xp < 0
print("Level:", level)
