WebEdges: a0-a1, a1-a2, a2-a3, a3-a4, a4-a5, a1-b1, a2-b2, a3-b3, a4-b4 Next vertexes have 3 degrees: a1, a2, a3, a4 Optimal solution is to remove a1-a2 and a3-a4 But if you remove a2-a3 on the first step you will need to remove extra two. So you can't randomly pick vertexes with max degrees. → Reply sidakbhatia 23 months ago, # ^ 0 Thank you-) Web1401D - Maximum Distributed Tree - CodeForces Solution.

Basically, start with the final array, and keep replacing an element with the 2 elements that xor-ed down to it, until you get the initial array. You'll see that the first element turns into a prefix, the second element turns into a subarray that follows this prefix, and so on.
WebYour task is to help AbdelKader find the minimum number of changes to the operators + and -, such that the equation becomes correct. You are allowed to replace any number of pluses with minuses, and any number of minuses with pluses.

This is an alternating binary string. † An alternating binary string is a string of 0 s and 1 s such that no two adjacent bits are equal. For example, 01010101, 101, 1 are alternating binary strings, but 0110, 0a0a0, 10100 are not. Input The input consists of multiple test cases.
