How is n-m =0 at timestamp 2:42
How is n-m=0 in the video
n-m <= 100000 which is given in the question.
but in the video prateek bhaiya told that m=50 and n=100 therefore n-m should be 50, but video says it is 0
He might have wanted to say something different or He might have mistaken it. It would be the difference between n and m.
