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. WebK'th Ancestor. You are given a tree of n nodes numbered from 0 to n-1 and is rooted at 0. You are given an array parent of length n where parent [i] denotes parent of i'th node (in case of root it's parent is itself). answer to this query is k'th ancistor of node a if k'th ancistor does not exist simply print root. designation of company representative
