The Vec::operator=(const Vec& original) method should:

• Check to see if original and I are different. (Hint: compare this and the address of original.) If they are different:
  1. Check to see if mySize is different from the size of original. If so (we need to make them the same size):
     1. Check to see if mySize is positive. If so (we need to deallocate our dynamic array):
        1. Deallocate the dynamic array whose address is in myArray.
        2. Set myArray to nullptr.
     2. Check to see if the size of original is positive. If so (we need to allocate an array the same size):
        1. allocate a new array that is the same size as that of original, and store its address in myArray.
     3. Set mySize to the size of original.
  2. Set the value of each item_i in myArray to the value of each item_i from original's array.
• Return myself (using *this).
