How to put this code below in the right format to answer the question


IF (a < b) THEN ! a < b here
IF (a < c) THEN ! a < c : a the smallest
IF (b < c) THEN ! b < c : a < b < c
cout << a, b, c
ELSE ! c <= b : a < c <= b
cout << a, c, b
END IF
ELSE ! a >= c : c <= a < b
cout << c, a, b
END IF
ELSE ! b <= a here
IF (b < c) THEN ! b < c : b the smallest
IF (a < c) THEN ! a < c : b <= a < c
cout << b, a, c
ELSE ! a >= c : b < c <= a
cout << b, c, a
END IF
ELSE ! c <= b : c <= b <= a
cout << c, b, a
