great logic!

Thank you , good concept

happiness=0 n,m=map(int,input().split()) array=list(map(int,input().split())) A=set(map(int,input().split())) B=set(map(int,input().split())) for i in array: if i in A: happiness+=1 elif i in B: happiness-=1 print(happiness)

why does some programs dosen't work in pypy3??

Thanks broo for a nice lecture..👍🙂

why should we use set in A and B and why we should not use list?

Why get n,m values??

HELP!! why it s not working in opposite manner where arr be converted into set

The explanation was really great but we should increase our video speed

what do you use to draw on a macbook? I'm just curious.

Question: what is the reason for mapping the n,m"s value?

i am from electronics abhi 4 din se python sikh raha hu but muje to hackerrank question hi samaj nahi aa rahe it is normal for everyone?

Hey i just doing the same thing but my compiler shows that i exceeded the time limit.

i am unable to understand last line of code

really helpful !!

how many easy level problems are there on python hackerrank

why dont u give size of array and sets ?

Bhi thora speed combine nhi karo.. thora process m karo ki samaj aa jaya.. App short hand bahut use karta ho..

you can simply use issubset() function
