LeetCode 1389按既定顺序创建目标数组(java)

class Solution { public int[] createTargetArray(int[] nums, int[] index) { List<Integer> list = new ArrayList<>(); for(int i = 0; i < index.length; i++) { list.add(index[i], nums[i]); } int [] res = new int[list.size()]; for(int i =0; i < res.length; i++) res[i] = list.get(i); return res; } }
