APPS#

Note

The Automated Programming Progress Standard, abbreviated APPS, consists of 10,000 coding problems in total, with 131,777 test cases for checking solutions and 232,421 ground-truth solutions written by humans. The data are split evenly into training and test sets, with 5,000 problems each.
The problems are curated from open-access sites where programmers share problems with each other, including Codewars, AtCoder, Kattis, and Codeforces.

# Definition

**_Strong number_** is the number that *the sum of the factorial of its digits is equal to number itself*.

## **_For example_**:  **_145_**, since 
```
1! + 4! + 5! = 1 + 24 + 120 = 145
```
So, **_145_** is a **_Strong number_**. 
____

# Task

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

# Input >> Output Examples


```
strong_num(1) ==> return "STRONG!!!!"
```

## **_Explanation_**:

Since , **_the sum of its digits' factorial of (1) is equal to number itself (1)_** , **_Then_** its a **_Strong_** .  
____

```
strong_num(123) ==> return "Not Strong !!"
```

## **_Explanation_**:

Since **_the sum of its digits' factorial of 1! + 2! + 3! = 9 is not equal to number itself (123)_** , **_Then_** it's  **_Not Strong_** . 
___

```
strong_num(2)  ==>  return "STRONG!!!!"
```

## **_Explanation_**:

Since **_the sum of its digits' factorial of 2! = 2 is equal to number itself (2)_** , **_Then_** its a **_Strong_** .  
____

```
strong_num(150) ==> return "Not Strong !!"
```

## **_Explanation_**:

Since **_the sum of its digits' factorial of 1! + 5! + 0! = 122 is not equal to number itself (150)_**, **_Then_** it's **_Not Strong_** .
