compareTwoStrings with arguments length lower than 3 since

[Flo0806]

Hello!

If I try to compare two strings like
compareTwoStrings("set", "st");
the result is always 0. Strings with length lower than 3 cannot be compared.

Is this normal?

Greatings!

In your example, 0 is the correct value of the Dice coefficient. The two string do not have any bigrams in common.

It can give non-zero results for strings of length two and three:

compareTwoStrings("abc", "abc") === 1
compareTwoStrings("abc", "ab") === compareTwoStrings("abc", "bc") === 2/3
