What is Output

[=?Utf-8?B?c2VlbWE=?=]

1) What will the value of txt be after executing MyFunction?

public void Main()
{
string txt = MyFunction( “12345� );
}

public string MyFunction( string str )
{
if( str.Length == 1 )
return str;
else
return MyFunction(str.Substring(1, str.Length - 1)) + str.Substring(0,1);
}
Hint:
String.Substring( startIndex, length )

seema,

Have you compiled this and seen what will be output?

It looks like someone doesn't want to do their own homework... will
eventually become a professional meeting attender (if not burger flipper).

Hi,

Just run it using the debugger

Bingo. The typographic quotes are a dead giveaway. =]

Not really a good hint as that gives no clue as to what will happen.
BTW, this is not the way I would code this, but it appears the goal was
to test the ability to follow a code path through a recursive function
without the aid of a debugger other than your internal debugger (the one
between your ears).

My Grandmother used to say that the way to learn about recursion is to study
recursion. She lived to be 100, by the way. It wasn't recursion that killed
her though. I think she had a stack overflow from some Clan McGregor scotch...
