validity,
because during the DFS a stack is brought in the parameter list to track
the string's validity. A Hashset result is used to check duplicates.
There are also ways to prune to find the invalidity earlier than removing
all 9 ( chars in each dfs tree, so O(C(17, 9) *n) is only the worst case.

Q:My child is too young to sign his/her own passport. How do I sign my child
's passport?
a:In the space provided for the signature, the mother or father must
print the child's name and sign their own name. Then, in parenthesis by the
parent's name, write the word (mother) or (father) so we know who signed for
the child. |
|
n*******2
发帖数: 10103 | 20 In order for the co-signature to be valid, the parent will have to sign their child's name and then their name next to it along with their relationship. In other words, it would read: child's name, parents' signature and then mother, father or guardian in parenthesis. The ideal situation would be that the parent that is signing the passport would actually be accompanying the child on the trip. This could alleviate any challenges that may be faced going through customs.
基本就是父母签 孩子名，父或母名（父亲或母亲） |
