Growth in 2 Dimensions

Problem Overview

• Determine how many cells hold the maximal value after applying range increments on an infinite 2D grid starting at (1,1).
• Input: String[] upRight, each entry "r c" adds 1 to all cells from (1,1) to (r,c) inclusive; Output: int count of cells with the highest value (constraints unspecified).
• Domain: matrix/grid updates modeling cumulative growth and data processing scenarios.
• From Ixl interviews; a classic coding interview problem and interview question.
