You are given a binary tree in which each node contains an integer value. Find the number of paths that sum to a given value. The path does not need to start or end at the root or a leaf, but it must go downwards (traveling only from parent nodes to
Description Yehan is a angry grumpy rabbit, who likes jumping into the hole. This day,Yehan jumps again in the pit at home. Each time, he should jump from the hole at the coordinate (1,1) to (n,m), and he has to jump as the way : he can only jump (x,
