题目167(Two Sum II - Input array is sorted): 问题描述:给定一个按升序排列的整数数组 numbers 和一个目标值 target,请你找出两个数使得它们的和正好是 target。返回这两个数的下标,下标从1开始。 条件:数组已排序。 Two Sum(未排序数组) 由于数组未排序,双指针方法无法直接应用。常见解法是使用哈希表(字典...

Two Sum II - Input array is sorted 解决思路 这题用sorted当做题目,好比路边的一些职业勾引男性行人,非常直接的就意味着二分搜索。一次查一半,所以刚开始只用到了二分搜索。但是有个问题,二分搜索的步子太大,可能把目标值跳过,那么还要借鉴双指针的全盘扫描的特点。
if (temp == target)先判断与目标数是否相同 可减少运行时间(因为Leetcode是拿很多不同数据来运行,而不是一条超长数据。仔细想想这里的区别) temp=numbers[i] + numbers[j]先把两数之和记录下来,像py3里那种判断两次(==、>)每次都计算一次两数和,会消耗更多时间,这在判断条件增多时会很明显。
