// Array Reversal
// Task

// Create a function reverseArray(array, length of array) . This reverseArray() will take two arguments - a dynamic uint type array and length of the array.
// The reverseArray() will reverse the array. For Example - If array =[2,5,9,11,1] then reverseArray() will return [1,11,9,5,2] If array =[90,20,30,10] then reverseArray() will return [10,30,20,90]
// Note - Function will be public.

// You can do this :)

            array[i] = array[length-i-1];
            array[length-i-1]=digit;
