arrays - Memory space consumption -

-

is there situation memory space taken linked list pointers more memory consumed array same problem if problem can solved both structures?

a linked list dynamically sized data, inserts , removes. typically on heap. comparing array mean array uses strategy being oversized unused entries inserts, , being reallocated if arrays threatens overflow.

so depends on actual array strategy , behavior of program, knowledge of it.

however every entry actual data needs space too, maybe pointer , allocated object. @ linked-list overhead form of indexing, in database. memory more or less irrelevant.

one should aware, instance linked list of booleans not clever.
