Hi, Kosal,

That's what you have: 

list1 = {{A, B, C}, {D, E, F}, {G, H, II}}
list2 = {{1, 2}, {3, 4}, {5, 6}}

This gives you the list of last elements of the first list (II instead of I, since I is the imaginary unity):

Last /@ list1

Out[29]= {C, F, II}

Then this solves your problem:

In[28]:= MapThread[Append, {list2, Last /@ list1}]

Out[28]= {{1, 2, C}, {3, 4, F}, {5, 6, II}}

Have fun, Alexei

Hello Mathematica users

I am new to Mathematica and I have one particular problem I would like you to help me.
Suppose I have two lists:

    list1 = {{A,B,C},{D,E,F},{G,H,I}}
    list2 = {{1,2},{3,4},{5,6}}

I want to have the third elements in each of member list in list1 (that is, C,F,I) to appear in the first position in each member list in list2

that is, i want to have  list ={{C,1,2},{F,3,4},{I,5,6}}

 Thank you.
