Check If Grid Satisfies Conditions

Determine whether a small grid satisfies a set of local cell-by-cell constraints.

Acceptance 0%

Start Practice

Problem Statement

Given an $m \times n$ grid of integers, check whether it satisfies a set of local conditions involving each cell and its neighboring cells.

In this problem, you inspect the grid directly and verify that every required condition holds. The task is primarily about careful iteration over the matrix and correctly handling boundaries when comparing neighboring values.

Return whether the grid satisfies all conditions.

Input Format

An integer grid with $m$ rows and $n$ columns.
Each cell contains an integer value.
The exact validity rule is determined by the problem statement for each cell and its adjacent cells.

Output Format

Return true if the grid satisfies all required conditions.
Otherwise, return false.

Constraints

The grid size is finite and small enough for direct iteration.
Values are integers.
Boundary cells must be handled safely when checking neighbors.
