maximum of 10 digits and ask if there is no prefix where a phone number is another phone number. Output no; otherwise, output Yes Ideas: The initial idea is to first add all characters to the trie tree at a time in ascending order of the string length. If a node has been marked as a string, no is output. Such an idea is TLE. This is probably because the length o

HDU1671 Phone List (Dictionary tree) Question: If you enter multiple string numbers, you must determine whether some numeric strings are prefix of other strings. If NO output exists, otherwise YES is output. Solution: Create a dictionary tree with trie, mark 1 at the end of each digit string, and then judge each input string. Whether there is a flag mark. # Incl

Main topic:Enter multiple strings of numbers to determine if the number string is the prefix of the other strings. If output no is present, the output is yes.Problem Solving Ideas:Use Trie to build a dictionary tree, then Mark 1 at the end of each number string, and then judge each string by entering it. Whether there is a previous sign mark. #include The following code does not use a dictionary tree:#inclu

This is also a simple application of the dictionary tree, but it is not a letter, but a number.The question is whether the input string will be prefixed with another string. It's that simple.The following is the code for AC:#include Hangzhou Electric Acm1671--phone list~~ dictionary tree

think that P is a legitimate pointer, and if the program is longer, we usually check the p! before using a pointer =null, this will not work. At this point, if you release the space that P points to, the compiler will give an error because it is illegal to release a space that has been freed. It is not problematic to set it to null and then re-release it because the delete one 0 pointer is safe.#include #include#include#include#includestring>#include#include#includeSet>#include#include#include#
