Now u can clearly see that optimal strategy is not the one with maximum moves. → Reply WebThe classic Problem. The most common application of binary lifting is the following: "Let be a rooted tree with nodes. For queries of the form we want to find the -th ancestor of in the tree." One simple, yet quite inefficient way of solving this problem is to build for every node an edge towards its direct ancestor. simple cotton wedding gowns

"WebIt isn't optimal to teleport to any node however we can compare path from 1 to 2 having XOR value = 2 and path from 3 to 2 having the XOR value equal to 2. In that case we don't teleport but if we had to, we would teleport from node 2 to node 2. Alternatively what the functions actually checks is all the possible XOR values starting from a and b.
