How to use Map inside Select

Question

Input:

Select[Range[10], 2 <= # <= 5 || 8 <= # <= 10 &]

Output:

{2, 3, 4, 5, 8, 9, 10}

In case I have lots of conditions I want to have them defined separately like this:

Input:

cond = {{2, 5}, {8, 10}};
Or @@ (#[[1]] <= q <= #[[2]] & /@ cond)

Output:

2 <= q <= 5 || 8 <= q <= 10

How to combine my first input with my second input to have all the code in my formula?

Answer 1

You could use Cases with a Condition:

Cases[Range[10], q_ /; 2<=q<=5||8<=q<=10]

{2, 3, 4, 5, 8, 9, 10}

or Select with a pure Function:

Select[Range[10], Function[q, 2<=q<=5||8<=q<=10]]

{2, 3, 4, 5, 8, 9, 10}
