-------------------------------
Summary: [C++] Fix the bug of parsing string hex values
Key: ARROW-7349
URL: https://issues.apache.org/jira/browse/ARROW-7349
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Liya Fan
Assignee: Liya Fan
std::lower_bound returns the end of the search range, when failing to find a
match.
The end of the search range is one position after the last valid position. So
the value in this position is undefined, and we should not reference the value
here to compare it with the target value.
