Diff function on two arrays (or how to turn Old into New)
Example
One[]={2,3,4,5,6,7}
Two[]={1,2,3,5,5,5,9}
Example Result
Diff: insert 1 into One[0], One[]={1,2,3,4,5,6,7}
Diff: delete 4 from One[3], One[]={1,2,3,5,6,7}
Diff: modify 6 into 5 in One[4], One[]={1,2,3,5,5,7}
Diff: modify 7 into 5 i
我非常喜欢使用,这是Ranges的一个实现。我特别喜欢每个STL算法上的可选投影。Invocable类型被转发(嗯.或者不是)像这样:()
template <ForwardIterator I, Sentinel<I> S,
class Comp = less<>, class Proj = identity>
requires
IndirectStrictWeakOrder<
Comp, projected<I, Proj>>()
I min_element(I first, S last, Com
这个循环很简单,但是我似乎不能用STL算法来给出下面相同的嵌套循环。
const int a_size = 5; // input
const int c_size = 2; // output
const int b_size = a_size * c_size; // multipliers
std::vector<float> a(a_size);
std::vector<float> b(b_size);
std::vector<float> c(c_size);
// fill a and b with data
// this nested
