John Watson knows of an operation called a right circular rotation on an array of integers. (Element\ in\ array) - (Number\ to\ find) = target\ value; Since the array is sorted, use binary search to find the element in the sorted array. Minimum no. You are given an array \(A\) of size \(N\). [Hackerrank] – Equal Stacks Solution. Please use list comprehensions rather than multiple loops, as a learning exercise. Hence, for a given element A, there will be at least A - Min(Array) moves to get to the solution.
