Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

So , here's the solution of this !!! U know that there are two places on my island where the two types of people will be found . But this is not known that who will be found where . So the question will be "Do you live here" How?? U know that if u will point on the place where the truthful people live and ask the question... then answer u will get by truthful _ "YES" and answer by a liar will also be _"YES" because he will lie . Now u also know that if u will be pointing on the place where the liars live and ask the same question then the answer by truthful person will be -"NO" and the answer given by liar person will also be -"NO" because he is a liar and will not say yes to the place where he actually lives . So. Pointing towards a truthful place and asking that question to anyone , the answer will be yes . And pointing towards a liar's place and asking that question to anyone , the answer u will get will be No. So taking inverse... if u are pointing to unknown place and asking that question, u will either get answer yes , than u will be understood that there live the truthful person . Or you will get answer No which means the place is that where liars live . So that question can tell u right places. @Calvin Lin
