Tofind a largest or maximum element of a vector, we can use*max_element() functionwhich is defined in<algorithm>header. It accepts a range of iterators from which we have to find the maximum / largest element and returns the iterator pointing the maximum element between the given range. ...
is the stride for vector x. Specified as: an integer. It can have any value. On Return Function value is the position i of the element in the array, where: If incx≥ 0, i is the position of the first occurrence. If incx < 0, i is the position of the last occurrence. Retur...
vector<int>v1(s1.begin(),s1.end());if(v1.size()==2)returnmax(v1[0],v1[1]);elseif(v1.size()==1)returnv1[0]; nth_element(v1.begin(),v1.end()-3,v1.end());returnv1[v1.size()-3]; } 最开始用set去掉重复元素。 nth_element是头文件algorithm中的函数,对vector进行升序快...
所以使用nth_element来处理。代码如下: intmaximumProduct(vector<int>&nums) {ints1=nums.size(); nth_element(nums.begin(),nums.begin(),nums.end());inta=nums[0]; nth_element(nums.begin(),nums.begin()+1,nums.end());intb=nums[1]; nth_element(nums.begin(),nums.end()-1,nums.end())...
Bike loves looking for the second maximum element in the sequence. The second maximum element in the sequence of distinct numbers x1, x2, …, xk (k > 1) is such maximum element xj, that the following inequality holds: . ...
In this paper, we propose a method of calculating an element of B-differential, also an element of Clarke generalized Jacobian, for a vector-valued maximum function. This calculation is required in many existing numerical methods for the solution of nonsmooth equations and for the nonsmooth ...
