Hi Yukti, the logic is not correct. You’ll always get true, because you’re just comparing the adjacent elements. The statement ‘if(ar[i]<ar[i+1] || ar[i]>ar[i+1])’ will give true even for 1 3 2 4 5 because for every adjacent pair of elements either of the two statements will give true. Try to think of something else.
