Easy

Problem Description

Multidimensional Array Element Count: Points Table Size

Learning Objective: Calculate total data volume with 2D array row and column counts

Check data scale of weekly points earning table. Use .length property of 2D array to get how many days of data exist (row count) and how many stores (column count), then calculate total point data count. Understand that numeric 2D arrays also use same length property.

Input

Line 1: Number of days n (1-3)
Following lines: Points for n days (3 stores per day: Store A Store B Store C)

Output

=== Points Table Size ===
Days: [n] days
Stores: [3] stores
━━━━━━━━━━━━━━━━
Total: [n×3] point data entries
```java

## Examples

### Example 1: Points table for 2 days
Input:
```java
2
10 20 30
15 25 35
```java
Output:
```java
=== Points Table Size ===
Days: 2 days
Stores: 3 stores
━━━━━━━━━━━━━━━━
Total: 6 point data entries
