leetcode 数组下标概率力码 [目录] 算法 1. 二和 Given an array of integers, return indices of the two numbers such that they add up to a specific target. 创建一个字典dic:target - nums[i] : i ,对列表进行遍历,如果nums[i]在dic中,则搜索成功。 dic = {} for i in range ( len ( nums )): if nums [ i ] in dic : return [ dic [ nums [ i ]], i ] else : dic [ target - nums [ i ]] = i ###2.添加两个数字 Input: (2 -> 4 -> 3) + (5 -> 6 -> 4) Output: 7 -> 0 -> 8 carry = 0 ans = cur = ListNode ( 0 ) while l1 or l2 or carry : if l1 : carry += l1 . val
