   • right - move the cursor to the right one character or do nothing if at the end of the line
   • left - move the cursor to the left one character or do nothing if at the end of the line
   • rdelete n - delete n characters to the right of the cursor
   • ldelete n - delete n characters to the left of the cursor
   • insert c - insert the character c just before the cursor Use 2 stacks to store the characters - one to store the chars to the left of the cursor and one to store the chars to the right of the cursor.
