F. Quadratic Set. For how to check whether it is the smallest, my approach is to record a minimum value _min, which represents the smallest cost among the ancestors, and then find the current point in two points, if it is less than _min , It means it can be exchanged. Similarly, count c1 as how many ones need to be changed into 0, and then greedy exchange is good, Note that if the quantity of 0 1 in b and c is not equal, you can output - 1 directly, Because pair does not support addition, I wrote a structure instead of pair, and overloaded addition and subtraction, which is more convenient, Posted by 0riole on Thu, 04 Jun 2020 08:16:17 -0700.
