Dice / Sorensen Metric - Incorrect Result? #29

Open AnanthaRajuC opened 7 years ago

AnanthaRajuC commented 7 years ago

for dice/sorensen metric, your example of "night", "natch" you are showing a value of .60, however according to the algorith the expected answer for the same two strings is .25

could you please elaborate on how you got .60?
