Can you solve this real interview question? Two Sum - Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may n
leetcode 1 Two Sum 详细解答 解法1 暴力解法,在这里使用双重for循环,遍历每一个数,来看两个数相加之和是否等于target。 代码如下: 时间复杂度:O(N2),空间复杂度:O(1) 解法2 上述解法时间复杂度过高,所以这里可以想到使用字典查询,使得查询变成O(1),因为要返回的是下标,所以字典存储的就是数字和对应的下标。
