Exercise: Smart Grid Energy Distributor

Explore how to apply Dart operators such as truncating division, modulo, and logical AND to solve a real-world problem involving energy distribution. Learn to calculate the number of fully charged batteries, leftover energy, and evaluate system stability without using if statements.

Problem statement

A smart solar grid distributes its generated power into standardized battery packs. The system needs to calculate how many batteries are fully charged and how much raw energy remains unallocated. The power grid enters a "stable surplus" state only if there are zero loose remaining kilowatts AND the number of full batteries is strictly greater than the designated reserve threshold. ...
