Useful!❤

[@oded6188]

They requested to solve it with O(n) but your are sorting the array so your solution is O(nlogn). Am I missing somthing?

[@harshitkumar8988]

No see must be wrong

[@mhamadfawaz4677]

Yes, exactly!

[@nitin_kaushik16]

Solution is pretty much cool, but I think O(n) time complexity solution must also be addressed in the video.

Hello Nitin,
Thank you for pointing that out. If you would like to share anything on that, please add it in the comments here. I highly appreciate it.

Approach 1:-
class Solution {
public:
int firstMissingPositive(vector& nums) {
int i,number=1;
sort(nums.begin(),nums.end());
for(i=0;i
