WRITE CODE THAT TAKES A TWO DEMINTIONAL LIST OF UNIQUE INTEGERS OF AT LEAST SIZE TWO FROM THE USER AND FINDS THE MINIMUM AND NEXT MINIMUM INTEGER IN THE TWO DEMINTIONAL LIST . WE WILL GUARANTEE ALL NUMBERS IN THE LIST ARE UNIQUE . RETURN THE TWO NUMBERS WITH DASH BETWEEN THEM FOR EXAMPLE IF THE USER ENTERS [[0,2],[4,1]] YOU WOULD RETURN 0-1 YOU MUST NOT USE ANY BUILT-IN FUNCTIONS/ METHODS BESIDE len() and append() [PLEAS USE DOUBLE WHILE LOOP FOR THIS PROBLEM]
