# Print Krishnamurthy number(also called Strong number) in given range using recursion

```				```
A Krishnamurthy number is a number whose sum of the factorial of digits is equal to the number itself.

eg,

145=1!+4!+5!

=1+24+120

=145

Hence, 145 IS KRISHNAMURTHY NUMBER
```
```
```				```
ENTER THE LOWER NUMBER
1
ENTER THE UPPER NUMBER
40585
KRISNAMURTHY NUMBER(S) BETWEEN 1 AND 40585:
1 2 145 40585
```
```
