An efficient tree-based data structure for detecting duplicate number values in fixed-length strings (e.g. phone numbers, national IDs, account numbers, etc.).

✨ Features

1. Fast: Detects duplicates in O(n) time complexity
2. Memory Efficient: Uses only O(d × L) memory (d = distinct strings, L = fixed length)
3. Simple and Clean
4. Zero Dependencies: No external libraries required
5. PHP 8.0+ Compatible

📦 Installation

```
  composer require alireza_malekei/number-expansion-tree:dev-main

```

🚀 Usage

Basic Example

```
  use Module\CircularChain;

  // List of phone numbers (fixed length: 10 digits)
  $phones = [
      '09138332910',
      '09135633375',
      '09138332910',
      '09138332910',
      '09135633375',
      '09121001010'
  ];

 $chain = new SoleDetectorTrie($phones); // Fixed length = 10

```

Total Count

```
  $chain->totalCount;

```

Output:

```
  6

```

Repeating Count

```
$chain->repeatingCount;

```

Output:

```
  3

```

Sole Count

```
$chain->soleCount;

```

Output:

```
  3

```

Repeating Entries

```
$chain->repeating;

```

Output:

```
09138332910
09138332910
09135633375

```

Sole Entries

```
$chain->soles:

```

Output:
