Solution: Flip Columns For Maximum Number of Equal Rows

Discover how to identify row patterns in a binary matrix and maximize the number of identical rows by flipping columns. Learn to implement a pattern-based solution using frequency mapping to achieve uniform rows efficiently within given constraints.

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 ...
