Two Sum Problem on leetcode
Hi guys, I can't seem to figure out what the problem is here:
class Solution {
public int[] twoSum(int[] nums, int target) {
int result [] = {0, 0};
List<Integer> original = new ArrayList<Integer>();
List<Integer> complement = new ArrayList<Integer>();
for (int i = 0; i < nums.length; i++) { original.add(nums[i]); complement.add(target - nums[i]);
} for (int i = 0; i < nums.length; i++) {
if (complement.contains(nums[i])) { int second = complement.indexOf(nums[i]); result [0] = i; result [1] = second; }
} return result; } } It does work for 62 out of 63 test cases but gives a wrong answer with the sets of [2, 4, 11, 3]. Just started learning programming, maybe I am missing something obvious? Thanks in advance.

Please format your code to make it more readable. For java, it should look like this:
Please tell what the method should do and what is the testcase that fails.
you get a set of numbers and a target number, you should figure it out which two numbers of the set have the sum of the target
just realised the problem was me being stupid tho 😄
forgot i can get negative numbers the way i did it
oi, ye not stupid mate
and that caused valid answers from my own sets...
Please close the post if done 😄
