Each empty box in the image above corresponds to a component of the array. These values are of the type int in this instance. The numbers 0 through 6 represent the position of the elements, with 0 being the first and 6 being the last. The index for the first element of the array in...
其实题目是一样的,同样是问是不是一个doubled array,而且已经是even number,数可以是负数,只需要返回true 或者false。 答案思路也是一样的。这里要用absolute来排序。 class Solution { public: bool canReorderDoubled(vector<int>& arr) { unordered_map<int, int> c; for (int i : arr) { c[i]++;...

Put all three elements in original into the first row of the constructed 2D array. Example 3: Input: original = [1,2], m = 1, n = 1 Output: [] Explanation: There are 2 elements in original. It is impossible to fit 2 elements in a 1x1 2D array, so return an empty 2D array....

Result for c++ dot: 2590046, time: 0.9966909885406494 不同的平台和系统得到的结果不一样,但应该可以稳定地观察到使用c++是快于python的。这里需要提一下,我们在python中传入了一个numpy array,但是c++接受的参数是个stl vector<int>。这是由于pybind11做了一些类型转换的工作使得这两个数据类型可以兼容。关于更多...
