I do not follow. The 'D' in 'letters' occur 1 time but it occurs
2 times in 'string'. So this is not the _exact number_ of
letters in the string.

So why now this fails when 'letters' has more N's than in string, but
the first case did not fail when 'letters' had less D's than in string?

I think your problem specifications is not clear.
