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

countMax has the following parameter$($s$)$: string uplightin$)$: an array of strings made of two space$-$separated integers, rand c

Return
