Solution: Lucky Numbers in a Matrix

Explore how to solve the lucky numbers problem in a matrix by applying graph theory and greedy algorithms. Understand the step-by-step process to find an element that is simultaneously the smallest in its row and largest in its column, and learn to implement this solution efficiently with O(m × n) time complexity and constant space.

Statement

Given an m×nm \times n matrix of distinct numbers, return the lucky number in the matrix.

lucky number is an element of the matrix such that it is the smallest element in its row and largest in its column.

Constraints:

  • m= ...
