Problem - Young Physicist

You have $n$ force vectors in 3D space, each with coordinates $(x, y, z)$. Your task: determine if they're in equilibrium, meaning their sum is the zero vector $(0, 0, 0)$. Output YES if balanced, NO otherwise.

This teaches you to work with multi-dimensional data and write functions that return boolean values. You'll sum vectors component-wise and check a condition, perfect for practicing function design.

Think about this before reading on: if you have forces $(1, 0, 0)$, $(-1, 2, 0)$, and $(0, -2, 0)$, are they balanced? What does balanced mean mathematically?
