I am halfly done right now, there are some quite easy question which you can solve in 10 minutes.
But there are few question that I gave up around one month ago.

These question are really nice to clear your concept and make you understand array and string better, especially how you handle them in your programming language.

I am using c++
For example,

To get a row and column for a 2D array vector<vector<int>> arr simply do

row = arr.size();
col = arr[0].size();

I started at 13 january and completed 57 easy and 10 medium questions at 2 march.

However, there is also some problem in the explore card
eventhough 561. Array Partition I is a good array question,
I dont see how is this question related to TWO-POINTER technique.

Have fun in coding, and see you in FAANG!
