Solution: Flip Columns For Maximum Number of Equal Rows

Understand how to maximize the number of identical rows in a binary matrix by flipping columns strategically. This lesson guides you through transforming rows into pattern strings and using frequency maps to determine the optimal solution efficiently, with clear explanation of time and space complexity.

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.
