Weak Test cases !! TAAND

just sorting an array and updating max for every two consecutive elements is getting accepted(100 marks) .

For the input 10 4 2 1 , answer according to above algorithm will be 0. (10&4 =0 , 4&2 = 0, 2&1 = 0) .

But the correct answer should be 10 & 2 = 2.

The solutions should be rejudged.

test case are too weak…contestants with this algo are being awarded complete 100 marks even if their codes are not even partially correct(their actual score must be 0).this is completely unfair on other contestants.

o/p for 3 2 4 10 should be 2 but its giving 0.
