The major trick is from another similar HR problem: subarray with max XOR: Build a binary tree bit by bit, and go from MSB to LSB, greedily. In this one, we need one more step before using that trick. We need do "rationally reason" and visualize it: we separate ints into 2 groups...
Key points for this one: - Relate the comparison process to BST search - Reasoning on extreme values: "We can notice that for a fixedthe maximum sum of depths is achieved when every node has just a left child and the minimum sum of depths os achieved when the binary tree is analmost ...
I'm excited to invite you to participate in101 Hack 47. The contest starts at1500 UTC, March 21.Note the unusual timing! All problems have been prepared by me. You might have seen some problems and contests set by me on various platforms. This is my third round on HackerRank, after101...
so he is representing the string saved indp[v]as a segment tree that carries the string hash of a range however finding the minimum between two strings is not that easy hence the hash comes into play he binary search the maximum prefix wherehash1[x][0 - > i] = hash[...

Depth First Search (DFS) - stack based, go as deep as possible then backtrack A balanced binary tree is a tree in which the height of the left and right subtrees differ by no more than 1 A complete binary tree is a tree in which every level, except possibly the last, is completely...
