Being a developer, you should know to process a large number of records with scripts. You are given records of *T* customers of compnay. Each record has the following information in the following format:

<customer_name>,<customer_no>, <date_of_birth>,<record _processing_date>

Where:

**<customer_name>**: Name of customer, can contain one or many spaces separated by tuples having English lowercase/uppercase letters. For example*"gopal"*and*"Ram Kumar"*(spaces can be more than one)**<customer_no>**: Enrollment number if customer, unique positive integer of atmost six digits.**<date_of_birth>**: Date of birth of customer, format is dd.mm.yyyy where 1 <= dd <= 30, 1 <= mm <= 12, 1980 <= yyyy <= 2030**<record_processing_date>**: Date of processing of record same format <date_of_birth>

Now the company wants to know the age of each customer to give them age specific offers. The age of the customer is calculated by counting the number of days between: **<record_processing_date>** and his **<date_of_birth>**

Given *T* such records, your task is to print the age (in number of days) of the customer for each record.

**Input Format**

- The first line has
*T*, the number of records - For next
*T*lines, each line has a customer record in the specified format.

**Constraints**

- 1 <= T <= 50
- All dates will be valid dates

**Output Format**

- For each record, print age (in number of days) of the customer

**Evaluation Parameters**

**Sample Input**

```
2
Ram Kumar, 134, 20.5.1994, 20.4.2002
gopal, 24, 31.12.1995, 21.02.2017
```

**Sample Output**

```
2892
7723
```

**Explanation**

The difference between dates 20.4.2002 and 20.5.1994 is 2921 days. And the difference between dates 21.02.2017 and 31.12.1995 is 7723 days.

The main occupation of the citizens of Numberland is to perform tasks on numbers. One such important task is finding interesting number sequences. As per the *Numberland Institute of Research*, an interesting sequence is defined as a sequence of numbers that are consecutive, for example:

```
1 2 3 4 5 6
10 11 12 13
```

are interesting sequences. Mathematically an interesting sequence has the following generic property: n*i*+1 = n*i+1*

The task faced by the research is as follows: Given an ordered set of distinct numbers, extract the length of the largest interesting sequence that can be obtained by rearranging the set of numbers.

Help the research the institute in finding the longest interesting subsequences.

**Input Format:**

- The input consists of two lines
- The first line contains N the length of the input sequence
- The second line of input contains of N numbers the sequence of numbers that must be analyzed

**Constraints:**

- 0 <= N <= 1000
- If K
*i*be ith element in the sequence, 1 <= K*i*<= 2000

**Evaluation Parameters**

**Sample Input**

```
11
15 17 13 16 14 3 4 6 1 2 5
```

**Sample Output**

```
6
```

Here we can re-arrange the sequence as

```
13 14 15 16 17 1 2 3 4 5 6
```

Observe that there are two interesting sequences

```
1 2 3 4 5 6
```

and

```
13 14 15 16 17
```

Sequence 1 2 3 4 5 6 is maximal length therefore the answer is 6
