This part is my memory, which can be omitted
Recall $SAM first$
In my understanding of $SAM $, first pick a picture
Initial string $aabbabd$
First, it is found that a straight line of $s - > 9 $in the figure below is $aabbabd $and $is the original string

strs=input('Please enter a string:')
for i in range(1,len(strs),2):
Enter the user name and judge whether the user name is legal (the length of th ...

Title Link: ybt gold navigation 2-1-3 / luogu P4555
General idea of the topic
Give you a string and ask you to find the longest substring so that it is composed of two palindrome strings.
First, let's see the palindrome string. Let's run a Manacher first.
Then we'll think about what to do. First, ...
