Upper Bound and Lower Bound in C++ STL | CP Course | EP 35

I have discussed Upper Bound and Lower Bound functions present in C++ STL in detail in this video for arrays, vectors, maps and sets.

Question To practice :
Upper Bound and Lower Bound questions are those of binary search only, So try solve all the easy and some easy medium in below lists. Please note that not all questions present in below links can be solved using upper_bound and lower_bound but most of the easy ones can be.

Allmost all other videos give knowledge but @luv gives knowledge with clarity and codes and very clean and simplified...

I had to use it in a question and searched for it but still could not understand it fully, but now it's clear

ARRAY SHOULD BE SORTED :

LOWER BOUND : If number is present, it will return pointer to number. If the number is not present, it will return the pointer to number greater than that.
Eg : 2 5 7 8 10 12
If we say lower bound 8, it will return pointer to 8.
If we say lower found 9, as 9 is not present, it will return pointer to next number greater than 9, i.e. 10.

Arey bhaiya kal hi street light wali problem m kiya tha lower_bound(set) and tle aya but ab samaj aya kyu and ho gaya solve, great help😃

[mjustboring]

binge-watching your videos on 2x or 1.5x... 😂😂
to just see the part which I don't know...
btw love your videos... keep it up...

[sleepypanda]

Thanks a lot helped me too solve many questions easily now! thanks really mean it

[garvgoel]

what is good practice -> to introduce an integer in loop and taking its input, or introducing the ineger before loop and then taking its inputs furtherly???

in loop case dose it makes 5 integres memory for loop of 5 or its one integer memry only??

[sagnikmitra]

Ye part mera sabse weak hai... Many many thnx for this video❤️❤️❤️

[bharatlakhera]

Last seens always amazing 🔥🔥
love u bro & thanku for your videos 💖

[whoisprafull]

Liked Videos and Loved Bloopers :) and thankyou so much bhaiiya .

[rohandas]

why do we need to sort the array to use upper and lower bound?

[holly]

Thank u bhaiya for such an amazing content

[shubhamgoswami]

Is it possible to find the lower or upper bound with the second value of vector of pair ?
if we can then we can resolve the issue of applying lower or upper bound in maps with non-key values .
