How will the above code work if

#1

I wanted to ask that as in the video Bhaiyaa has taken the elements as 0,1,2,3,4,5 and therfore in order but let’s say if i take the elements as 1 2 3 4 5 then also the above code will print 0 and many other test cases will be failed

#2

then u are required to start all the loops from 1 and not from 0
or else if u wish to start from 0
then u insert the nodes in a fashion that they start from 0
ie [1-1]-> [2-1]
so this was the nodes start from value 0
and then at the end when u need to print the answer
add 1
so that answer starts from 1
