Solution: Flip Columns For Maximum Number of Equal Rows

Understand how to maximize the number of equal rows in a binary matrix by flipping columns. Explore the method of creating pattern strings that group rows with matching elements, allowing identification of row sets that can be made identical. Learn how to implement this using a frequency map and analyze the time and space complexities involved.

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.
