You are almost there!

sscanf() requires you to give the format of the expected string to be parsed.

You have commas between numbers... Just try to add commas between the %d...

 "%d,%d,%d"

Option 1: use a combination of standard library functions such as strtok() and atoi(), or sscanf(). With these tools, you'll figure it out in no time!

Option 2: roll out your own function! It's a nice thinking excerise :).
