Input array = [3, 3, 3, 3], str = ' *++ ' Output 15 Explanation Using binary search to determine where to place the next value, the worst case time complexity of this approach is O(n log n). The total complexity of this should be O(nlogn), needing O(n) to create the dictionary, O(nlogn) for sorting, and O(n) for iterating the sorted values in that dictionary. So we can test our solutions. Our almost finished code turns out to be the following: Unfortunately we still have some silly issues to deal with to perfect our code. Usually, especially with BFS, you can just start with the initial value in a queue and then add new, intermediate values to the queue as they pop up, so the graph is just implied. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Is not listing papers published in predatory journals considered dishonest? Then for a solution to exist we must have B[1] = A[1] - B[0] + A[0], and the number of operations is abs(A[0] - B[0]) (or equivalently abs(A[1] - B[1])). Then you need to find the longest path in the graph using techniques from graph theory.
