主要思想: 数组可以无序 假设数字里的值都为正 循环判断数组 如果与前面的数字相同则变为-1 然后记录-1的个数算出重复值 然后重新new一个减去重复值长度的新数组 和原数组判断 不为-1的全部复制进来即可 代码如下: package Del_Same_Num; public class Del_Same_Num { static int count=0; //计算重复值 public static int count_same_number(int[] a) { for(int i=0;i<a…
Given a non-empty array of integers, every element appears twice except for one. Find that single one. Note: Your algorithm should have a linear runtime complexity. Could you implement it without using extra memory? Example 1: Input: [2,2,1] Output:…
一 ,var dataArr = []; var data = new Date(); var year = data.getFullYear(); data.setMonth(data.getMonth()+1, 1)//获取到当前月份,设置月份 for (var i = 0; i < 12; i++) { data.setMonth(data.getMonth() - 1);//每次循环一次 月份值减1 var m = data.getMonth() + 1; m = m < 10 ? &…
