1. Two Sum Description Given an array of integers, return indices of the two numbers such that they add up to a specific target.You may assume that each input would have exactly one solution, and you may not use the same element twice.Example: Given nums = [2, 7, 11, 15], target ...
In Python, the hash table we use is the dictionary. A simple implementation uses two iterations. In the first iteration, we add each element's value as a key and its index as a value to the hash table. Then, in the second iteration, we check if each element's complement (target - ...
在这种情况下,无论您的数字列表是长列表还是短列表,Python 在解决求和问题方面都非常有用。 如果您想通过从头开始创建自己的解决方案来对数字求和,那么您可以尝试使用for循环: >>> >>> numbers = [1, 2, 3, 4, 5] >>> total = 0 >>> for number in numbers: ...
你需要实现的函数twoSum需要返回这两个数的下标, 并且第一个下标小于第二个下标。注意这里下标的范围是 0 到 n-1。 样例 Example1: 给出numbers = [2, 7, 11, 15], target = 9, 返回 [0, 1]. Example2: 给出numbers = [15, 2, 7, 11], target = 9, 返回 [1, 2]. ...

3,要注意的一点是:在原来数组中找下标时,需要一个从头找,一个从尾找,要不无法通过。如这个例子:numbers=[0,1,2,0]; target=0。如果都从头开始找,就会有问题。 以下是我写的: class Solution: def twoSum(self, nums, target): """ :type nums: List[int] ...
