Expected output for Exercise 4 in Language Tutorials

[sariyuce]

I guess the expected output must be \"Denise\", \"Paras\" here, not \"Hank\", \"Denise\", \"Paras\" because \"Hank\" is a friend of \"Dave\" as noted in the Exercise 1.

"The correct answer contains three results: \"Hank\", \"Denise\", \"Paras\""

Same example is used for openCypher here, so it needs to be fixed too:

Line 842 in fb66141

"The correct answer contains three results: \"Hank\", \"Denise\", \"Paras\""

Hank is a direct friend of Dave and also a direct friend of Josh, who in turn is a friend of Dave. The question simply asks to find the friends of Dave's friends without any requirement to exclude people who are already direct friends of Dave. Therefore, the expected output of "Hank", "Denise", and "Paras" is correct.

This is about "Exercise 4: Which friends should we recommend for Dave?", not Exercise 2.
