-1投票 带有嵌套向量的代码 您使用嵌套向量的代码看起来是正确的: class Solution { public: bool isSubsetSum(vector<int> arr, int sum) { int n = arr.size(); vector<vector<bool>> dp(n + 1, vector<bool>(sum + 1)); for(int i = 0; i <= n; i++) dp[i][0] = true; // ...

在C++中,`std::vector`是一个动态数组,它可以根据需要自动调整大小。`std::vector`不能使用前向声明,是因为在编译时需要知道元素的确切大小。 当使用前向声明时,编译器只知道该...
