Solution: Flip Columns For Maximum Number of Equal Rows

Explore how to solve the problem of maximizing identical rows in a binary matrix by flipping columns. Understand how to create standardized row patterns, use frequency mapping to track patterns, and determine the maximum achievable identical rows efficiently with O(m×n) time 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.
