What does faultyLocation mean?

[BEbillionaireUSD]

I assume the faultyLocation.txt contains the indices of faulty lines, but I found that the indices can refer to empty lines.
For example, in abc280_f/Java/42792826/faultyVersion.java, the faultyLocation.txt contains 165, but the 165th line is an empty line (if we index the first line with #1).

163. boolean unite(int u,int v,long c){
164. assert valid(u,v,c);
165.
166.     if ((u = root(u)) == (v = root(v)))
167.       return false;

Did I miss something or you have a different indexing manner?

Your assumption about the faultyLocation.txt file is correct. In this version, the correct fix is to add code at line 165, which is why line 165 is marked as faulty
