Today is your and your twin sibling’s birthday. To celebrate, you got a rectangular cake to share. The cake is decorated with NN triangular patches of icing (which may overlap). All the icing patches were created with the same triangular mold, so they have the same shape and orientation. Although you and your twin are very similar, your tastes in icing are much different. This difference is formalized by each of you having a different enjoyment value for each patch of icing. Specifically, your enjoyment value for eating the entire ii ⁠-⁠th patch of icing is AiAi , and your twin’s is BiBi . If someone eats part of a patch, they get enjoyment proportional to the eaten area. For example, if you eat 2323 of the area of the ii ⁠-⁠th icing patch, you would get 2Ai32Ai3 enjoyment from it. Note that there may be some flavors of icing that you or your twin do not enjoy, so the AiAi and/or BiBi values can be negative. Read More »

This problem is about finding the distance between two nodes of a strictly binary tree. Oh, is that too easy?! Ok, the tree is potentially infinite now. Keep it up and we will start going up the aleph numbers. In this problem, a tree is either a single node XX , or a node XX with two trees attached to it: a left subtree and a right subtree. In both cases, XX is the root of the tree. If the tree is not a single node, the roots of both the left and right subtrees are the only children of XX . Read More »

divisible divisions codejam solution For Solution Click Here! We have a string SS consisting of decimal digits. A division of SS is created by dividing SS into contiguous substrings. For example, if SS is 0145217, two possible divisions are 014 5 21 7 and 0 14 52 17. Each digit must be used in exactly one substring, and each substring must be non-empty. If SS has LL digits, then there are exactly 2L−12L−1 possible divisions …
