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deftwoSum(nums, tar
PYTHON 方法/步骤 1 新建一个PY文档，打开JUPTER NOTEBOOK。2 #Given nums = [2, 7, 11, 15], target = 9nums = [2, 7, 11, 15]target = 9我们要找出列表里面两个相加数为目标的数字。3 nums = [2, 7, 11, 15]target = 9nums2 = numsfor a, j in enumerate(nums): for b, k in ...
python 实现一个TwoSum的例子 1819 今天无意中看到一个题目,也不是很难,就想着用python实现以下: 题目是数组中的两个数相加等于输入的一个target,然后输出数组的下标。 比如: [1,2,3,4,5,6] target=7 返回[1,4] 主要是坑就是避免有重复的数字 代码如下 1 2 3 4 5 6 7 8 9 10 11 12 13 14 ...
