Fast*er* string comparison - an alternative to thousands of strcmp calls
|
Fast*er* string comparison - an alternative to thousands of strcmp calls
|
||||||
|
|
||||||
|
This is an O(n) solution - n being the length of the string to be checked.
|
||||||
|
A plus is that this method will stay O(n) *no matter the length of the string
|
||||||
|
nor the number of strings to be checked against*.
|
||||||
|
|
||||||
|
Potential minuses might be the additional memory needed to store the trie
|
||||||
|
data structure or the computational time required to generate the tree before
|
||||||
|
utilizing it. Therefore, users are advised to use a secure, fast hashmap
|
||||||
|
instead of streecmp. streecmp is only applied to specific scenarios where
|
||||||
|
a rather simple or fast solution for string comparison is required so the
|
||||||
|
project moves on.
