Two sequences are in x and y. I choose A and B and extract (and put in z) the values
of x such that the corresponding values of y are included between A and B

<= y <=     x separated by "," ↑   -   y separated by "," ↓        

z: output ↓

Esempi       In x:  1,2,3,4,5,6    In y:  0,1,1,0,1,0    1 <= y <= 1  →  z:  2, 3, 5
In x:  132,89,110,210,75    In y:  53,49,112,100,95    50 <= y <= 100  →  z: 132, 210, 75
[C]   cancella x e y     [Cz]   cancella z
