I get [28 0 9 2 26 7] for test case 2 and [0 13 0 0 0 11] for test case 3.

Tim,
I am not quite sure where did that amp came from in test-2.
it wasn't in my original test suite.
in test-3, grave accent is not a punctuation mark - so far i know.

For some reason, according to Matlab function isstrprop, the characters $ + < = > ^ ` | ~ are not considered to be punctuation marks, or letters, or digits, or anything else--this seems to be discriminatory and unjust.

This problem has an interesting take on punctuation characters.
