Modify a matrix by applying a per-cell transformation rule to each element.
Problem
Given a 2D matrix, produce a modified matrix by applying a rule to each cell. The exact transformation depends on the problem’s specification, but the core task is to inspect the matrix, compute a replacement value for each entry, and return the transformed grid.
This problem is mainly about careful matrix iteration, handling boundary conditions, and constructing the resulting matrix correctly.
What to focus on
- Traversing every cell in a 2D grid
- Correctly handling row and column boundaries
- Building the output matrix without corrupting needed input values
- Keeping the implementation clean and linear in the number of cells
Input Format
- A 2D integer matrix
matrixwithmrows andncolumns. - Additional transformation rules are applied cell by cell as defined by the problem.
Output Format
- Return the transformed 2D matrix after applying the required modification rule to every cell.
Constraints
- The matrix contains a finite number of rows and columns.
- Each cell should be processed consistently according to the given rule.
- Aim for time unless the rule suggests otherwise.
Example 1
Input
matrix = [[1,2],[3,4]]
Output
[[1,2],[3,4]]
Explanation
Illustrative example showing the expected matrix format. The actual modification rule depends on the problem definition.
