NPE bugs in MaximumProductOfWordLengths.java and RemoveDuplicatesFromSortedArray.java

[HermioneSW]

Hi,

I have found two bugs in MaximumProductOfWordLengths.java (leetcode/bit-manipulation/MaximumProductOfWordLengths.java) and RemoveDuplicatesFromSortedArray.java(leetcode/two-pointers/RemoveDuplicatesFromSortedArray.java).

In MaximumProductOfWordLengths.java line 20 if(words.length == 0 || words == null) if words is null, words.length will NPE

Similarly in RemoveDuplicatesFromSortedArray.java line 12 if(nums.length == 0 || nums == null) if nums is null then nums.length will NPE.

I know they are minor issues. I would still be good if you can fix them. Thanks a lot!
