Statement of problem E is misleading. I was thinking about arbitrary values of the nodes but not the indexes of the nodes.

    Yes but anyway still doable, given E was nothing but value of node i is i. But coming to the misleading I didn't mentioned special values of nodes in the Statement and in sample tests too so I thought no one will confuse. But sorry for that inconvenience
