WebThe total number of nodes and edges is O(n) due to the observations. Basically, we always have that c(10) + c(00) and c(01) + c(11) are fixed because the string b doesn't change, and after an even number of operations we also have c(10) + c(11) is fixed because two operations is just a swap. From these three equations, the count c(10) uniquely ...
