___
# Task

**_Given_** a number, **_Find if it is Tidy or not_** .

___

# Notes 


* **_Number_** *passed is always*  **_Positive_** .

* **_Return_** *the result as* a **_Boolean_** 

~~~if:prolog
* Since prolog doesn't have booleans,  return value should be 1 for (True) or 0 for (false)

# Input >> Output Examples

```
tidyNumber (12) ==> return (true)
```

## **_Explanation_**:

**_The number's digits_**    `{ 1 , 2 }`  are *in non-Decreasing Order* (i.e) *1 <= 2* .
____

```
tidyNumber (32) ==> return (false)
```

## **_Explanation_**:

**_The Number's Digits_**  `{ 3, 2}`  are **_not in non-Decreasing Order_** (i.e) *3 > 2* .
___

```
tidyNumber (1024) ==> return (false)
```

## **_Explanation_**:

**_The Number's Digits_**  `{1 , 0, 2, 4}`  are **_not in non-Decreasing Order_**  as  *0 <= 1* .

___

```
tidyNumber (13579) ==> return (true)
```

## **_Explanation_**:

**_The number's digits_**    `{1 , 3, 5, 7, 9}`  are *in non-Decreasing Order* .
____

```
tidyNumber (2335) ==> return (true)
```

## **_Explanation_**:

**_The number's digits_**    `{2 , 3, 3, 5}`  are *in non-Decreasing Order* , **_Note_**   *3 <= 3*
