std::sort面试

回答: 在C++中使用std::sort函数对容器进行排序是一种常见的操作。可以直接调用std::sort函数，并传入起始迭代器和结尾迭代器来对容器进行排序。例如，可以使用以下代码对deque容器进行排序：

#include <iostream>
#include <deque>
#include <algorithm>

using namespace std;

template<typename T>
void sort_stdalg(deque<T>& dq) {
std::sort(dq.begin(),dq.end());
}

int main() {
deque<int> dq = {4, 2, 3, 1};
sort_stdalg(dq);
for (int num : dq) {
cout << num << " ";
}
// 输出: 1 2 3 4
return 0;
}

< sorted[j - 1]) {
T t = sorted[j];
sorted[j = sorted[j - 1];
sorted[j - 1 = t;
}
}
}
return sorted;
}

int main() {
constexpr std::array<int, 4> before{4, 2, 3, 1};
constexpr std::array<int, 4> after = Sort(before);
static_assert(after == 1);
static_assert(after == 2);
static_assert(after == 3);
static_assert(after == 4);
return 0;
}

<span class="em">1</span><span class="em">2</span><span class="em">3</span>
