Solution: Flip Columns For Maximum Number of Equal Rows

Explore a method to determine the maximum number of rows with identical values in a binary matrix after flipping any number of columns. Understand how to apply pattern mapping by comparing row elements to detect flip equivalences and count frequency. This lesson helps you implement an efficient solution with O(m×n) time complexity for matrix problems involving column manipulation.

Statement

Given an m×nm \times n binary matrix, matrix, return the maximum number of rows where all values become identical after flipping any number of columns. Flipping a column means changing every 00 to 11 and every 11 to 00 in that column.
