Problem $1$ A two$-$dimensional integer array named sales holds the weekly sales for employees in a jewelry store for a year. Implement a method named salesRange$()$ that returns an array containing three statistical values: $1.$ the lowest sale amount, $2.$ the highest sale amount, and $3.$ a value representing the range of sales held in the array, i$.$e$.$ the value of the highest sales amount minus the value of the lowest amount $.$ The method takes a two$-$dimensional array of integers named sales, as a parameter. $($For example, if sales holds the values below:

$200350400$

$150375225$

the method should return $[150,400,250].$
