求大神帮忙。我run时显示Runtime Error,不知道问题在哪里。。
还有,我也不理解注释中的: * Note: The returned array must be malloced, assume caller calls free(). 这句是什么意思
题目:
Given an array of integers, find two numbers such that they add up to a specific target number.
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.
Input: numbers={2, 7, 11, 15}, target=9
Output: index1=1, index2=2

/**
- Note: The returned array must be malloced, assume caller calls free(). / int twoSum(int* nums, int numsSize, int target) { int i,j; int index1,index2; for(i=0;i<numsSize;i++) { for(j=0;j<numsSize;j++) { if(nums[i]!=0 && nums[j]!=0) { if(nums[i]+nums[j]==target) { if(nums[i]<=nums[j]) { index1=i+1; index2=j+1; } else { index1=j+1; index2=i+1; } } } } } printf("[%d,%d]",index1,index2); }
