To sort a mixed list of strings and numbers, you cando the following.> big_list := [1,"d",3,5,2,"a","c","b",9];big_list := [1, “d”, 3, 5, 2, “a”, “c”, “b”, 9]Make two lists from the original, one consisting of numbers and oneconsisting of strings.> list1 := select( type, big_list, string );list1 := [“d”, “a”, “c”, “b”]> list2 := select( type, big_list, numeric );list2 := [1, 3, 5, 2, 9]Then sort the two lists independently.> list1 := sort(list1);
