DIY Tree codeforces solution – William really likes puzzle kits. For one of his birthdays, his friends gifted him a complete undirected edge-weighted graph consisting of nn vertices. 100% correct solution

William really likes puzzle kits. For one of his birthdays, his friends gifted him a complete undirected edge-weighted graph consisting of nn vertices.  He wants to build a spanning tree of this graph, such that for the first kk vertices the following condition is satisfied: the degree of a vertex with index ii does not exceed didi. Vertices from k+1k+1 to nn may have any degree. … Read more

As mentioned previously William really likes playing video games. In one of his favorite games, the player character is in a universe where every planet is designated by a binary number from 00 to 2n−12n−1. On each planet, there are gates that allow the player to move from planet ii to planet jj if the binary representations of ii and jj differ in exactly one bit. 100% correct solution

William has two arrays aa and bb, each consisting of nn items. For some segments l..rl..r of these arrays William wants to know if it is possible to equalize the values of items in these segments using a balancing operation. Formally, the values are equalized if for each ii from ll to rr holds ai=biai=bi. Equilibrium solution codeforces To perform a balancing operation an even number of indices must be selected, such that l≤pos1 100% correct solution

You are given a binary string binary. A subsequence of binary is considered good if it is not empty and has no leading zeros (with the exception of “0”). Find the number of unique good subsequences of binary. For example, if binary = “001”, then all the good subsequences are [“0”, “0”, “1”], so the unique good subsequences are “0” and “1”. Note that subsequences “00”, “01”, and “001” are not good because they have leading zeros. Number of Unique Good Subsequences solution leetcode 100% correct solution
