How to | Combine and Rearrange Lists
Mathematica provides a complete data manipulation language with vast flexibility in rearranging lists with any number of elements in any kind of structure.
Set up a list of six integers with some duplicates (stored as ):
 Out[1]=
Sort the elements of the list :
 Out[2]=
Use Union to sort and remove any duplicates:
 Out[3]=
Note that unless you redefine , it retains its original value:
 Out[4]=
Redefine :
 Out[5]=
 Out[6]=
Reverse the order of :
 Out[7]=
Rotate the elements of two places to the left:
 Out[8]=
Rotate the elements of two places to the right:
 Out[9]=
Pad on the left with to get a list of length 10:
 Out[10]=
Partition the list into sublists of length 2:
 Out[11]=
Partition the list into sublists of length 2 with offset 1:
 Out[12]=
Split a list into runs of identical elements:
 Out[13]=
Flatten deletes inner braces in nested lists:
 Out[14]=
Join the elements of a set of lists:
 Out[15]=
