# leetCode 26.Remove Duplicates from Sorted Array(删除数组重复点) 解题思路和方法

Remove Duplicates from Sorted Array

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 nums = [1,1,2],

Your function should return length = 2, with the first two elements of nums being 1 and 2 respectively. It doesn‘t matter what you leave beyond the new length.

```public class Solution {
public int removeDuplicates(int[] nums) {
if(nums.length <= 1){
return nums.length;
}
int len = 1;//新的长度，至少为1,以下循环从i=1开始
for(int i = 1; i < nums.length; i++){
if(nums[i] != nums[i-1]){//不等于前一个元素，长度+1
nums[len++] = nums[i];//将新的元素装到前len个
}
}
return len;
}
}```
