Hey bro.... You helped me a lot with this video. Do you explain with javascript as well?

We can also use hashset to solve this question Hashset gives all unique elements from an array

[kuruvellateju]

Bro iam not able to get the logic fadtly iam not able to think thatvwe can do with two points i, j😢

[shanyasharma]

It is showing an error
error: cannot find symbol
int n = nums.size();
^
symbol: method size()
location: variable nums of type int[]

[ashu]

we can also do it without using two pointer
class Solution {
public int removeDuplicates(int[] nums) {

int k=1;

for(int i=1;i<nums.length;i++){
if(nums[i]!=nums[i-1]){
nums[k]=nums[i]
;
k=k+1;
}
}
return k;
}
public void main (String[] args){
int []n1={1, 1, 2};

}
}
