SpOT-fast code error

[Sprate]

Hi, Ni Trieu. When I increase the expectedIntersection, I found two errors in your code.
1.In two choice hash, when you swap the bin positions of two values, their hash indexes should be reversed.
So in BalancedIndex.cpp, the above code might be append.

2.In MultiThread setting, when insert the final results into globalHash, you might forget to lock the thread in your code.
It happens in PrtySender.cpp line 252, the above code might be right.
