Supercells

What is a Supercell?

In a grid of numbers, a cell is called a Supercell (or is “coloured”) if the number inside it is larger than numbers in all adjacent cells.

• 1D (Row) Case: Check left and right.
• 2D (Grid) Case: Check top, bottom, left, and right.

Example

Consider the following row: $200 \quad 577 \quad 626 \quad 345 \quad 790 \quad 694 \quad 109 \quad 198$

Let’s check specific numbers:

1. 626: Neighbors are $577$ and $345$. Since $626 > 577$ AND $626 > 345$, 626 is a Supercell.
2. 200: Neighbor is $577$. $200 < 577$. Not a Supercell.
3. 198 (End): Neighbor is $109$. $198 > 109$. 198 is a Supercell.
