1:53 -- literally me😂😂
What does that even mean.

[@ujjwalagnihotri5001]

What is the meaning of without loss of generality which you explained in problem C?

[@Harisamsharma]

It means that we can make some assumption safely, without losing any information about the problem

[@siddhantmishra4944]

I did not understand one thing- Why
if(i != n){
break ;}.
Why this i != n ?

[@s_3095]

@harisam please can you tell me what's needed to get par with these diV3 B AND C PROBLEM. I mean what rating to practise and what's needed to solve them

[@monty6393]

That 2nd problem uhhhh!!!.. Still I am wondering how 3451 .. for k = 1 became 3450 why 1 got decremented by 1 and became 0?

[@rahulv12s27]

They have given round x to kth digit right?

[@kannank4269]

Count k starting starting from 0 from right to left

[@monty6393]

Thanks for the reply , but it's seems like my mind gave up in understanding the problem statement..

[@Entertainmentexe]

Keep it up

[@ayushanandtripathi352]

For problem F, why 2 values of ai is not possible when ai = (-b +- d)/2a

[@Harisamsharma]

Since aj = x - ai, the value of aj is exactly equal to (-b-d)/2a
