然后再去遍历数组,如果当前元素为正数,则说明其所在索引没有遇见过,就将其添加进list中。 publicList<Integer>findDisappearedNumbers3(int[] nums){ List<Integer> list =newArrayList<Integer>();if(nums ==null|| nums.length <1) {returnlist; }for(inti =0; i < nums.length; i++) {intval = Math...
然后判断新数组中,那些等于0的元素的索引就是nums中缺失的数。 publicList<Integer>findDisappearedNumbers2(int[]nums){List<Integer>list=newArrayList<Integer>();if(nums==null||nums.length<1){returnlist;}int[]temp=newint[nums.length+1];for(intnum:nums){temp[num]++;}for(inti=1;i<temp.length;...

Given an array of integers where 1 ≤ a[i] ≤ n (n = size of array), some elements appear twice and others appear once. Find all the elements of [1, n] inclusive that do not appear in this array. Could you do it without extra space and in O(n) runtime? You may assume the ...
LeetCode-Find All Numbers Disappeared in an Array Description: Given an array of integers where 1 ≤ a[i] ≤ n (n = size of array), some elements appear twice and others appear once. Find all the elements of [1, n] inclusive that do not appear in this array....
这道题让我们找出数组中所有消失的数,跟之前那道Find All Duplicates in an Array极其类似,那道题让找出所有重复的数字,这道题让找不存在的数,这类问题的一个重要条件就是1 ≤ a[i] ≤ n (n = size of array),不然很难在O(1)空间和O(n)时间内完成。三种解法也跟之前题目的解法极其类似。首先来看第...
