1 sortA( sortA( list name)
Sorts lists in ascending order.
Example
• Store list {2, 7, 4} in L1, and
sort L1 in ascending order.
2 sortD( sortD( list name)
Sorts lists in descending order.
Example
• Sort the above list L1 in
descending order.

performed on the first list as a key, and the following lists are
sorted in the order corresponding to the elements in first list (key
list).
Example
• Store lists {2, 7, 4} and { - 3, - 4,
- 1} in L1 and L2 respectively,
and sort L1 and L2 in ascend-
ing order using list L1 as a
key list.
