首先,需要创建一个函数,它接受两个参数:一个整数数组和一个目标值。该函数将用于查找数组中相加和等于目标值的两个数字。 登录后复制deftwoSum(nums, target): 接下来,需要初始化两个变量登录后复制i和登录后复制j,分别设为 0。这两个变量将用于跟踪数组中相加和等于目标值的两个数字的索引。 登录后复制deftwo...
1、Two Sum(两数之和) 1、这道题目比较简单,是求给定的数组nums中,找到其中两个不同数字相加为给定值target。然后将这两个数字的下标返回即可。直接通过暴力搜索,AC这道题。 C语言: C++: python: 初次写文章,以此来记录自己的学习过程,共勉。...

Python应用之基础算法第一篇:Two sum 最近一直考虑着下一篇关于Python的文章应该是什么样的内容,对比一些专业大咖的文章,目前应该写一个完整的且无错的程序,然后和大家一起一行行地分析代码相互学习,可是我实在不想如此亦步亦趋。在学习编程方面,我是一个实用主义者,认为“学以致用”才是学习的最终目的, 最近发现...
