**Java String Tokens**

### Problem Statement :

Given a string, s, matching the regular expression [A-Za-z !,?._'@]+, split the string into tokens. We define a token to be one or more consecutive English alphabetic letters. Then, print the number of tokens, followed by each token on a new line. Note: You may find the String.split method helpful in completing this challenge. Input Format A single string, s. Constraints 1 <= length of s <= 4.10^5 s is composed of any of the following: English alphabetic letters, blank spaces, exclamation points (!), commas (,), question marks (?), periods (.), underscores (_), apostrophes ('), and at symbols (@). Output Format On the first line, print an integer, n, denoting the number of tokens in string s(they do not need to be unique). Next, print each of the n tokens on a new line in the same order as they appear in input string s.

### Solution :

` ````
Solution in C :
import java.util.*;
class Solution {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String input = scan.nextLine().trim();
scan.close();
String[] tokens = input.split("[^\\p{Alpha}]+");
int size = (input.isEmpty()) ? 0 : tokens.length;
System.out.println(size);
for(String s : tokens) {
System.out.println(s);
}
}
}
```

## Counting On a Tree

Taylor loves trees, and this new challenge has him stumped! Consider a tree, t, consisting of n nodes. Each node is numbered from 1 to n, and each node i has an integer, ci, attached to it. A query on tree t takes the form w x y z. To process a query, you must print the count of ordered pairs of integers ( i , j ) such that the following four conditions are all satisfied: the path from n
