we can modify the previous answer to make it efficient...
check it..
string x = "asdfsdaaasasa";
string output = "";
int count = 0;
IEnumerator ie = x.GetEnumerator();
IEnumerator iee = x.GetEnumerator();
while(ie.MoveNext())
{
if (!output.Contains(ie.Current.ToString()))
{
while(iee.MoveNext())
{
if ((char)ie.Current == (char)iee.Current)
{
count++;
}
}
iee.Reset();
output = output + count + ie.Current;
count = 0;
}
}
Console.WriteLine(output);
