Subject: [PATCH] Update merge_sorted_arrays.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Comparator 'greater' should also include the type.
Compilation fails with the following error.
error: wrong number of template arguments (0, should be 1)
priority_queue<IteratorCurrAndEnd, vector greater<> > min_heap;
Proposed change is to simply include the type.
Using the following compiler version:
g++ --version;
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix
