# Update

1. Update `gen.bash` script so that it can handle more than 9 pieces of test data. Because of `sed` does not support **lazy match** (aka. non-greedy match) so I turn to `perl`.

2. There seems to be a bug in integer sanitizer in clang, which cause the program (exactly problem 2 solution) outputs different result. So I turn off it. But I do not file a bug to llvm for laziness!
