10921 - Find the Telephone

[CyberPunk]

why do I have to read one character at a time? what's wrong with my current code?

[brianfry713]

Try input Z output should be 9.

Why WA?

AC, thanks brianfry. :D

But when I use scanf %s and a for loop, I got AC.

[brianfry713]

don't print an extra blank line at the end.

For 11385, see http://acm.uva.es/board/viewtopic.php?t=27378
For 10921, at the end of the input you're calling trim() on a null pointer.

Print a newline char at the end of each line.
