Max Area of Island
Write `max_area_of_island(grid)` returning the number of cells in the largest connected group of `1`s, or `0` when there is no land. The grid holds integers.
Identical traversal to Number of Islands — the only change is that the flood counts the cells it visits and returns that, and the outer loop keeps a running maximum.
What to expect: A timer starts when you begin. Edit the starter code, run it against the test suite as many times as you like, then finish when you're done. The reference solution and interviewer follow-up questions unlock only after you finish.
