LISP nested Loops perform in parallel. How would one force it to perform sequentially? -


I have been learning Lisp slowly since the last two weeks. I have come in a situation where lisp presents two loops in parallel, and what I am not aiming for. If I understand correctly, what I want to achieve will be classified sequentially. To give you an idea of ​​what happens to you, we can take a look at the following: 

  (for 'y') (in '(ABCDE)' in the loop ('1 2 3 4 5') )   
 With this type of coding, one will get:  
  (A1) (B2) (C3) (D4) (E5))   
 But what I want is:  
  (A1) (A2) (A3) (A4 What changes would I need to make with this loop to get the desired result? (A5) (B1) (B2) (B3) and so on   
I am wrong to use the word "successively", please correct me. I am studying on it, but I have a hard time.   
 
 
 You need a nested loop:  
  (loop 'x' in 'abcde') nconc (y 'loop' (1 2 3 4) 5) Collect (list xy))

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
