(10 pts) Write a method to find out the height of the tree (we do not maintain height as a parameter in either the Node or the BSTree) (10 pts) You want to write a function RangeRemoval for an array that will have two parameter low and high value defining a range of integers (you can assume the second parameter is less than or equal to the third parameter), and an array. Your task is to remove all values in the array, whose elements are between the second and third parameters, inclusive, from the parameter list. For example, if the array were of size 12 and was as follows: [0,1,2,4,5,7,8,9,11,12,15,17 and your second and third parameters were 6 and 12, respectively, then the parameter list becomes: [0,1,2,4,5,15,17,_]
