Write a function that receives a StaticArray that is sorted in either non$-$descending or

non$-$ascending order. The function will return the mode $($the most$-$occurring element$)$ of the

array and its frequency $($how many times it appears$).$

If there is more than one element that has the highest frequency, select the one that occurs

first in the array.

You may assume that the input array will contain one or more homogeneous elements

$($either all numbers, or strings, or custom objects, but never a mix of these$).$ You do not

need to write checks for these conditions.

For full credit, the function must be implemented with O$($N$)$ complexity, with
