Codeforces Round 714 Div2 || Fast Solving A, B, C but not getting D || FaceCam + Commentary

So, here is the screencast for today's Div2 round on codeforces. I had solved A, B, C relatively fast but then could not get D. Tried some segment tree + lazy propagation but didn't work out.

[@saurabhsingh6325]

When he said "Not getting D" I felt that

[@ParitoshPotukuchi]

Priyansh. For C I thought of building an m X 9 table which has the value for each digit from 1 to 9 for all values of m. Then for each digit refer to the table and add the values.

[@PriyanshAgarwal]

[@learningfoundation6601]

the only thing i got after seeing these type of videos that : it is not beneficiary to any competitive programmer as you even not tells how would you came to think that the main thing in cp you have to put of diff methods that came in your mind as soon as you think just skills show off. its hard but please think over it

[@noobie6784]

u got a new fan!!!!

[@piyushgaur6975]

In problem C, line 118 of your solution can you please Elaborate what are those predefined function mod_add() ???

[@PriyanshAgarwal]

mod_add() is not a predefined function. It is a function that I have created in my template. It just adds 2 numbers and returns the answer modulo some number.

[@bishakhdutta8427]

@@PriyanshAgarwal can you share your template?

[@Saitama-kf4oy]

[@yt_shubham_bgp]

It comes with practice

[@PriyanshAgarwal]

Try to solve many 1200-1600 problems and you will start developing speed.

[@joydeepdas4105]

[@nikhilgautam2857]

[@PriyanshAgarwal]

I use a plugin SublimeAStyleFormatter I guess and it auto indents the code when I save/build it.

[@saurabhnikam]

Hello priyansh,many beginners who stuck in problem B,C div 2,3. can u make video about prerequisite tools methods (based on ur experience so far) e.g. prefix sum,1-d dp,brute force, tough implementation approach like.... to tackle them since u where so much comfortable 🙌🙌 in this difficulty level.plz think on it it will be so helpful for us

[@PriyanshAgarwal]

Sure, I will make a video on this thing as soon as I get time. Thanks for the suggestion
