The test to see if this is correct doesn't work. If you just code 'b = 0' then it is always correct!

I get the correct answers for this, but the website refuses to tell me it is correct. Fix this dumb stuff.

@Harley, MATLAB functions are case sensitive. Did you try lowercase sum?

In fact this problem can be solved by only using sscanf and str2num.
