I am trying to take elements from a list of tuples using 2 criteria. An example of the list is:
list={{-1, -1}, {-1, 1}, {1, 1}, {1, -1}, {1, (1 + I)/Sqrt[2]}}
And I need to take the elements that contain one value $=1$ and a second value $\neq1$. Thus at the end, I will have
list2={{-1, 1}, {1, -1}, {1, (1 + I)/Sqrt[2]}}
I`ve been trying using select as
list2 = Flatten[Table[Select[list[[i]], # == 1 &, 2]], {i, 1,5}], 1];
but the problem is that the values $=1$ do not have a "fixed column". Is there a way to do this avoiding an "if" statement?. Thanks in advance.
