    Bhaiya 30:43 pe apne shayad jaldi mein ye thoda galat bol diya, map mein elements hum kisi bhi order mein push karen to order preserve nahi hota, but sorted order mein push hota.
    Naye logon ke liye for example, yahan humne babbar, mera aur phir unknown push kiya, ye already sorted hain isliye output esa aya but agar hum for example mera ko babbar ke pehle push kardete to bhi output babbar, mera aur unknown hi ata, kyunki lexicographically 'babbar' 'mera' se pehle store hoga map mein.

    If the key values in a std::map are strings, the sorting is performed based on the lexicographical order of the keys. The std::map class uses the comparison operator< by default to determine the order of elements.

    bhaiyaa consistency kab ayegi phli ki tarah. apna course kab tk complete ho payega .Placements season bhi close hai . Bhaiiya this course was really amazing till now but ab thoda sa slow paced ho gya I personally feel that.
    Bakkki the course went very well till now but when will we will start getting tutorials about the main topics like The Graphs, dp tries, backtracking and others when will the videos of those start getting uploaded on our channel and in our course.
    Bhiayya please bring back our old form consistency back again for our this super ultimate course 🎯🤩🙏🙏

I was able to pass the test somehow but my curiosity brought me here and I learned all the concepts regarding hashmaps from your video. Now I am confident about my knowledge of hashmaps and surely I will do better in any other future exams.
