2. Write a method, rangeBuilder(), that takes two integer parameters m and n. The method should create an array of
integers with n-m+1 elements. You may assume that n is greater than m. Fill the array with the integer values m,
m+1, m+2, ... n and return the filled array. For example if called with rangeBuilder(4,6), the method would return
an array of 3 elements containing 4 at index 0, 5 at index 1, and 6 at index 2.
