} 发现对于leetcode而言貌似只能提交class Solution内部的部分。而compare函数放在Solution内部就会出错,放在Solution外面就正常。为什么??? 然后就通过重载圆括号写了函数对象,顺利通过。 1classSolution {//two sum O(nlogn)2public:3structNode{4intval;5intindex;6Node(intv,intidx) :val(v), index(idx){}7...

The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than index2. Please note that your returned answers (both index1 and index2) are not zero-based. You may assume that each input would have exactly one solution....
