Algorithm to compute maximum of blocks

We have $n$ numbers lying on a circle, where $n$ is even. We want to compute the maximum of any $n/2$ consecutive numbers (so, we should get $n$ values in total). One algorithm is to compute the max …

Algorithm to maximize $j-i$ subject to $A[j]>A[i]$

We want an algorithm that, given an array $A$ of length $n$ of integers (indexed by $A[0],A[1],\ldots,A[n-1]$, determine values $i<j$ that maximizes $j-i $ subject to $A[j]>A[i]$ (if such values $i,j$ …
