Growth in $2$ Dimensions

Start with an infinite two dimensional grid filled with zeros, indexed from $(1,1)$ at the bottom left corner with coordinates increasing toward the top and right. Given a series of coordinates $($r$,$ c where r is the ending row and cis the ending column, add $1$ to each element in the range from $(1,1)$ to $($r$,$ c$)$ inclusive. Once all coordinates are processed, determine how many cells contain the maximal value in the grid.

Function Description

Complete the function countMax in the editor below
