泛型Lambda,代码如下: const auto l = [](auto a, auto b, auto c) {}; // is equivalent to struct anonymous { template <class T0, class T1, class T2> auto operator()(T0 a, T1 b, T2 c) const { } }; 在C++ 14中引入的泛型Lambda,它可以使用auto标识符捕获参数。可变泛型Lambda,代码如...

In column, A you have the final result, but the recursion goes back up to the n=2 (column D), so you should read it from column D (n=2) to column C (n=3), etc. so the formula does this backward calculation until the entire recursion is expanded up to the end n=2. On each...
