That's my biggest pet peeve ever. Reading a question (especially math!) wrong. I absolutely hate when I do it.
Ah, reading again the M.ANAND KUMAR post I understand that he wanted to use any digit in his 8 digits phone number. Sorry, I was wrong, I thought that the 8 digits are constant. Your answer is correct.
I don't think that's right.
You just need to be careful if you're given a word with repeated letters, like 'deeded'.
