WebSep 28, 2024 · Then, we can apply divide and conquer DP. The optimal "splitting point" for a fixed i increases as j increases. This lets us solve for all states more efficiently. Say we compute o p t ( i, j) for some fixed i and j . Then for any j ′ < j we know that o p t ( i, j ′) ≤ o p t ( i, j) . This means when computing o p t ( i, j ′) , we don't ...

WebJun 8, 2024 · Lowest Common Ancestor - Binary Lifting Let $G$ be a tree. For every query of the form (u, v) we want to find the lowest common ancestor of the nodes u and v , … WebBinary jumping is more commonly referred to as "binary lifting." Solution To solve this problem, we can use a standard binary lifting implementation where jmp (int x, int d) corresponds to the d d -th ancestor of x x. In our jmp (int x, int d) if our final value of x x is 0 0, then such a node does not exist and we can simply return -1 −1. income from form 8889
