How to make this code work for negative numbers

#1

I tried this program for [-2,-2,1,1,-3,1,-3,-3,-4,-2]
but this is not working for this data set.

#2

well it should work! can you share the code

#3

Take type as long long (for -ve integers are represented as 2’s complement!)

#5

bhaiya i was trying same question another platform if you could help for it, even after chnaging to long long it isnt working.

Don’t use a while loop!


moreover here long long is not necessary as input fits into int(32 bit)

#7

ohhhh okayy we are not using while(n>0) becuase no.s are already negavite they will all be <0 ?

#8

but the code above which was taught in the cb video uses while no>0 and works fine for negavite numbers, what is the logic behind not using while(no>0)

#9

Yes you will not count bits in that case!

#10

There must be some modification (if it works) because you have implemented yourself and seen the failure.

#11

how do one gets to know the mistake they are doing? like i was doing it well but somehow failed in the analysis part while debugging how not to do these mistakes?

#12

Dear Naman, there is no formula to it, it comes naturally by lots of practice.

#13

okayyy, thanks a lot. Will work on this then.
