Hi
I have a problem.
I have a list.
testList={ {11,{2,3}},{21,{3,4}},{34,{5,6}},{51,{7,8}} }
1) From this list, select any element list such as {x,{3,4}},
where X is an arbitrary number.
In general, position of {x,{3,4}} in "testList" is not fixed.
2) Select any element list such as {x,{3,4}} and then exchange {x,{3,4}} to {100,{3,4}}.
3)Make a new list finally.
testListNew={ {11,{2,3}},{100,{3,4}},{34,{5,6}},{51,{7,8}} }
Please teach me how to solve.
Thanks in advance.
