What are the C++14 parts here? I haven't been paying much attention to the C++14 standards shaking out.
dfrey already asked about why begin/end are functions now.
I see auto being used inside the lambda. Was that not allowed in C++11? I got sucked into the "use auto everywhere" mantra, so I just imagined it was possible, but could easily see if it were not. That is probably the biggest decrease in size to the original code posted.
I see return type inference. That is one thing I have heard about being new in C++14. To be honest, I would rather see the explicit return type there. Inference is always nice, though.
- bstamour 13y agoI omitted the return type (which is allowed for lambdas in C++11, and now arbitrary functions (with some conditions) in C++14) because it was a 1-liner. The bool return type can be deduced by the compiler automatically (or else it would fail to compile) and by the human by the operator < in use, the fact that it's being passed to sort, etc.

- dmunoz 13y agoThanks for the reply. A comment under the accepted answer points to the wikipedia article on C++14, which has information on the new language and new standard library features [0]. I should have thought to check there first. [0] https://en.wikipedia.org/wiki/C%2B%2B14 https://en.wikipedia.org/wiki/C%2B%2B14
