to convert two list

[robierzo]

Hello. I need to convert two lists with mapcar, lambda.....

Example:

 
(setq lista '((1.236 (5 10)) (5.3214 (4 9)) (7.6541 (12 63))))

Convert to:

 
'((5 10) (4 9) (12 63))

Is that possible?

Can not be used FOREACH!!!

Regards

Try this ...

 

(mapcar (function (lambda (x) (setq l (cons (cdr x) l)))) '((1.236 (5 10)) (5.3214 (4 9)) (7.6541 (12 63))))
(apply 'append (reverse l))

 

With the use of foreach function .

 

(foreach x '((1.236 (5 10)) (5.3214 (4 9)) (7.6541 (12 63))) (setq lst (cons (cdr x) lst)))
(apply 'append (reverse lst))
