I was wondering if there is any way to solve the following problem: ↵
↵
_" You are given a network graph. Every edge has two values associated with it: the upper bound of the amount of flow that CAN go through this edge and the lower bound of the amount of flow that MUST go through this edge. If there is no valid way to satisfy lower bound of all the edges, print "Unsolvable" . If there are multiple ways, maximize the amount of flow satisfying the lower bounds and upper bounds. You have to report the maximum amount and also the amount of flows through individual edges. "_ ↵

NoI don't know of any online judge that has this problem ( at least none that I know of ). It's a random problem that came to my mind. ↵
