Solution: Flip Columns For Maximum Number of Equal Rows

Understand how to transform binary matrix rows by flipping columns to maximize identical rows. Learn to identify row patterns, implement frequency mapping, and optimize time and space complexity in matrix operations.

We'll cover the following...

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 ...
