因为要求是返回修改后的长度并只考虑该长度的数组,那么就不用考虑该长度之后的数组,所以只需得到索引 j 的值,不用再把索引 j 的值改为索引 i的值。 Java: 代码语言:txt 复制 class Solution { public int removeElement(int[] nums, int val) { int i=0,j=nums.length-1;//i-左指针;j-右指针 whil...
Remove Element leetcode java 题目: Given an array and a value, remove all instances of that value in place and return the new length. The order of elements can be changed. It doesn't matter what you leave beyond the new length. 题解: 这道题跟remove duplicate sorted array是一样的。。。

因此新的方法更适合容易出现异常条件的情况。 peek,element区别: element() 和 peek() 用于在队列的头部查询元素。与 remove() 方法类似,在队列为空时, element() 抛出一个异常,而 peek() 返回 null。
