Bhaiya, coming from a middle-class family with mediocre teachers, I have always thought I would never get placed due to the fact that I could not afford courses and the difficulty of problem-solving. All of us are blessed to have you as a savior. Thank you very much. I am part of the 2020-2024 batch, and my placements will begin in July. As a result of discovering your channel and starting to prepare, my hopes have been revived. You will make a huge difference in my life if I get a job and can provide for my family.

C++ can overload the [] operator, so i assumed when you do arr[i], it does traverse until i and get the data for you. But yeah, I'm at fault, considering how everyone interchangeably uses array and vector, i should have guessed vector is prob dynamic array and not linked list.

Simply amazing, i have an interview two days later. Love your way of explaining.

This is literally the best video for learning C++ STL. Thanks Striver :)

This is the best youtube video I've come across. Productive one hour.

Thank You Striver ! Wanted to learn STL from a long time but couldn't complete due to the lengthiness of courses available. You gave us the precise idea of stuff that is actually necessary for regular use, Thank YOU !

This was my first time learning STL, and bingo ! That was very easy, idk if someone else would have taught like this. Day 5 of Striver A2Z DSA Course Completed ✅

Your teaching style is superb. 👌 I've been following your videos since a few weeks and I'm learning dsa on my own pace. Thanks a lot for all your videos. Keep helping juniors. Thanks a lot!

Has everything that's required and yet explained in such a clear and structured manner! Amazing video sir 👍👍

ITs been a long time approx 4 years since I started my career in software development. Started again with dsa to upgrade my self. Thank you Striver.

Bhaiya Just a small correction at 45:00 you wrote ms.find(1) + 2 in the end part of the erase() function. But this will give us an error because only array, vector, and string can store elements in contiguous memory locations, so we can't do +2 and access the element after the first occurrence of 1. Here is the corrected code for that part: auto it = ms.find(1); advance(it, 2); /* Now the iterator is one position ahead of where you want it to be. This is because in the erase() function it takes from the start till one element less than the end that we specified.*/ ms.erase(ms.find(1), it); // Now we have the iterator in the correct place so it will erase properly and we will be left with only one 1.

​@@creepopsub2936 iterators are of different type. the rend() member function returns an iterator of type std::vector::reverse_iterator, which gives an error when you try to store in a variable it2 of type std::vector::iterator. Just simply write std::vector::reverse_iterator its2 = v.rend() instead an it will work. As iterators come in varieties (std::vector::cont_iterator to name one), It becomes tedious and an error-prone way to always explicitly define iterator type when declaring a variable. So I'd advice you to use auto keyword instead. It saves you from writing verbose iterator type-names and prevents errors from creeping into your code.
