Suppose We have 5 number 2277,4004,11,23,583835,1010 and we need to create password from these.
Conditions are:

password = Sum of all stable numbers - Sum of all Unstable numbers

where stable numbers are the numbers those who have same frequency/occurrence of every digit in the number.
And Unstable numbers are those who have different frequency/occurrence of digits in number.

the method should look like

public int findpassword(int input1,int input2,int input3,int input4,int input5)
{
}

What I have tried:

I can check for a single number whether it is stable or not buthow could I check for all the numbers passed through a function argument whether they are sable or not?

## Solution 1

Change method to
```public int findpassword(params int[] input)
{
if(input == null)
throw new ArgumentNullException(nameof(input));

for(int i=0; i < input.Length; i++)
{
}
}```

maybe?

I am supposed to do with that function only that's where the main challenge.

```public int findpassword(int input1,int input2,int input3,int input4,int input5)
{
{
if(input == null)
throw new ArgumentNullException(nameof(input));

for(int i=0; i < input.Length; i++)
{
// Do Stuff
}
}

var result = findpassword(new int[] { input1, input2, input3, input4, input5 });
}
```

Thank you for the help.I am working with C# 5.0 where nested functions are not allowed as I saw in some articles.Anyways thank you sir.

Nested functions are only a compiler trick... The compiler will create a second private method out of the nested one... A thing which you can also do.

It's the same thing, only with params you don't have to name each argument individually, and you can pass as many or as few arguments as you need.

But ... if your homework requires you to use that exact method signature, then start by writing a method which takes an integer, and returns a bool:
C#
```private static bool IsStable(int value)
{
...
}```
Then call that five times in your code:
C#
```int stableCnt = 0;
int unstableCnt = 0;
if (IsStable(input1)) stableCnt++;
else unstableCnt++;
if (IsStable(input2)) stableCnt++;
else unstableCnt++;
...```
