/*从数组中删除指定定数据var somearray = ["mon", "tue", "wed", "thur"]somearray.removeByValue("tue");//somearray will now have "mon", "wed", "thur"*/Array.prototype.removeByValue = functi
题目:比较传入函数的参数,将参数组成数组,从小到大排序,返回新的数组. 如: insert();console.log(arr); //[] insert(-1,-2); console.log(arr);//[-2,-1] insert(3);console.log(arr);//[-2,-1,3] insert(6,4,5);console.log(arr); //[-2,-1,3,4,5,6] 代码实现: var arr = []; var index = 0; function inse
Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example,Given input array A =[1
Follow up for "Remove Duplicates":What if duplicates are allowed at most twice? For example,Given sorted array A =[1,1,1,2,2,3], Your function should return length =5, and A is now[1,1,2,2,3]. 题意:可以保留一个重复的元素. 思路:第一种是和Remove duplicates from sorte
