One day Nikita found the string containing letters "a" and "B" only.
Nikita thinks that string are beautiful if it can be cut into 3 strings (possibly empty) without changing the order of the Letters, where the 1-st and the 3-RD one contain only letters "a" and the 2-nd contains only letters "B".
Nikita wants to make the string beautiful by removing some (possibly none) of its characters, but without changing their o Rder. What is the maximum length of the the string he can get?

The prefix infix suffix expression in computer is an important application of data structure stack, they are the notation of the expression, but the relative position is not the same as the name implies, the prefix expression refers to the symbols are in the operand before the infix expression refers to operators are operands, after the suffix expression is after. Such as:
(a+b) *c-d is an infix expression
For example, a string ababc
First, regardless of the null character, all prefixes have a, AB, ABA, Abab, ABABC, where the true prefix has a, AB, ABA, ABAB
In the same way, the suffix is understood, and the true prefix is the first (back) prefix that does not contain itself.
The prefix function Next[j] refers to the

Trie Tree, also known as the Dictionary tree, prefix tree. Can be used for "predictive text" and "Autocompletion", can also be used for statistical frequency (side insert trie tree Edge Update or add word frequency).In computer science,Trie, also known as a prefix tree or a dictionary tree , is an ordered tree that holds associative arrays, where the keys are usually strings. Unlike a two-fork lookup tree,

They are all expressions. The difference between them is that the operators are different from the locations of the operands: the operators of the prefix expressions are located before their related operands; the same is true for the infix and suffix.Convert an infix expression to a

say a few, it must be split into several three, and the rest is split into two. the requirements for this question cannot be the same, so it must be arranged in the order of 2, 3, and 4. Starting from 2, it will make it smaller, so that the number will be the most, and adding one at a time will make him closer and closer. So with prefix and record, if there is surplus, it must be from the back one by one + 1, and the remaining number can be at most =
Test instructions: Returns the longest common prefix of these strings to multiple strings.Idea: The number of characters in the same position is counted directly, if there are only 1, then that bit is the same and goes to the next comparison. Otherwise terminates the comparison and returns the prefix. There may be a shorter string, so the longest prefix is only t
