Binary Lifting is a dynamic programming approach where we pre-compute an array memo [1, n] [1, log (n)] where memo [i] [j] contains 2^j-th ancestor of node i. For computing the values of memo [] [], the following recursion may be used memo state: memo [i] [j] = i-th node’s 2^ (j)th ancestor in the path memo initialization: WebAuthor: Anil Altinay.
