How to extract elements from a Table

Question

I was trying to find the maximum of a function and where it maximises. I found that FindMaximum will give the result. Now I need to save the maximum value and x value(using replace rule) in two different variables.

I have a Table like this:

T1 = {  0.686151, x -> 1.54793, 0.686075, x -> 1.55549, 0.687346, 
 x -> 1.54975, 0.689603, x -> 1.52983, 0.692579, 
 x -> 1.49448, 0.696075, x -> 1.44192, 0.699942, 
 x -> 1.36952, 0.704069, x -> 1.27328, 0.708369, 
 x -> 1.14652, 0.712778, x -> 0.976704, 0.717245, 
 x -> 0.733626, 0.721731, x -> 0.256813, 0.726028, 
 x -> 1.84992*10^-9, 0.729878, x -> 1.01046*10^-9, 0.733336, 
 x -> 4.23067*10^-7, 0.736454, x -> 1.1326*10^-8, 0.739275, 
 x -> 5.37651*10^-10, 0.741835, x -> 9.37745*10^-6, 0.744167, 
 x -> 3.23782*10^-6, 0.746296, x -> 1.28956*10^-6, 0.748245, 
 x -> 5.7631*10^-7, 0.750034, x -> 2.82576*10^-7, 0.75168, 
 x -> 1.49276*10^-7, 0.753197, x -> 8.37318*10^-8, 0.754599, 
 x -> 4.92927*10^-8, 0.755898, x -> 3.01754*10^-8, 0.757103, 
 x -> 1.90688*10^-8, 0.758222, x -> 1.23672*10^-8, 0.759265, 
 x -> 8.19418*10^-9, 0.760237, x -> 5.52643*10^-9, 0.761145, 
 x -> 3.78294*10^-9, 0.761994, x -> 2.62213*10^-9, 0.76279, 
 x -> 1.83701*10^-9, 0.763537, x -> 1.29881*10^-9, 0.764238, 
 x -> 9.25594*10^-10, 0.764898, x -> 6.64199*10^-10};

and I need this:

T2 =  {{0.686151}, {0.686075}, {0.687346}, {0.689603}, {0.692579}, \
{0.696075}, {0.699942}, {0.704069}, {0.708369}, {0.712778}, \
{0.717245}, {0.721731}, {0.726028}, {0.729878}, {0.733336}, \
{0.736454}, {0.739275}, {0.741835}, {0.744167}, {0.746296}, \
{0.748245}, {0.750034}, {0.75168}, {0.753197}, {0.754599}, \
{0.755898}, {0.757103}, {0.758222}, {0.759265}, {0.760237}, \
{0.761145}, {0.761994}, {0.76279}, {0.763537}, {0.764238}, {0.764898}};

T3 = {  x -> 1.54793, x -> 1.55549, 
 x -> 1.54975, x -> 1.52983, 
 x -> 1.49448,x -> 1.44192,

Please help me out

Thanks in advance

Answer 1

T1 = {0.686151,x->1.54793,0.686075,x->1.55549,0.687346,x->1.54975,0.689603,x->1.52983,0.692579,x->1.49448,0.696075,x->1.44192,0.699942,x->1.36952,0.704069,x->1.27328,0.708369,x->1.14652,0.712778,x->0.976704,0.717245,x->0.733626,0.721731,x->0.256813,0.726028,x->1.84992*10^-9,0.729878,x->1.01046*10^-9,0.733336,x->4.23067*10^-7,0.736454,x->1.1326*10^-8,0.739275,x->5.37651*10^-10,0.741835,x->9.37745*10^-6,0.744167,x->3.23782*10^-6,0.746296,x->1.28956*10^-6,0.748245,x->5.7631*10^-7,0.750034,x->2.82576*10^-7,0.75168,x->1.49276*10^-7,0.753197,x->8.37318*10^-8,0.754599,x->4.92927*10^-8,0.755898,x->3.01754*10^-8,0.757103,x->1.90688*10^-8,0.758222,x->1.23672*10^-8,0.759265,x->8.19418*10^-9,0.760237,x->5.52643*10^-9,0.761145,x->3.78294*10^-9,0.761994,x->2.62213*10^-9,0.76279,x->1.83701*10^-9,0.763537,x->1.29881*10^-9,0.764238,x->9.25594*10^-10,0.764898,x->6.64199*10^-10};

Then

{T2, T3} = GatherBy[T1, Head]

Or alternatively

pos = Drop[Position[T1, Rule, {2}], 0, -1];
T2 = Delete[T1, pos];
T3 = Extract[T1, pos];

Answer 2

{T2a, T3} = T1[[# ;; ;; 2]] & /@ {1, 2};

or

{T2b, T3b} = Pick[T1, Head /@ T1, #] & /@ {Real, Rule}

{T2a == T2b, T3 == T3b}

{True, True}

T2 = List/ @ T2a

Answer 3

Since you seem to be separating based on Rule:

Cases[t1, x : Except[_Rule] :> {x}]
Cases[t1, _Rule]
