vector<int> nums {2,7,11,15};inttarget=9;//vector<int> nums {1,2,2,4,1,4};cout<<s1.twoSum(nums,target)<<endl;return0; } python解法: 之前一直不知道python如何输入数组,现在知道input可以处理所有类型,但是因为输入是字符串所以都要转化。hash表结构可以直接用{}实现 nums=list(map(int, i...

2. Add Two Numbers——Python 题目: You are given two linked lists representing two non-negative numbers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. Input:(2 -> 4 -> 3) + (5 -> 6 -...

Thereduce()function is a built-in function in Python that can be used to apply a given function to all elements of a list. To add two numbers, you can use thereduce()function along with theoperator.addfunction. # Importing the operator module and the reduce function from functools library...
