Question: Here is a binary tree. Each node has a w value. Now there is a small ball with the value of x, which is dropped from the root node. If w = x, it will stop; if w> x, the probability of its son going to the left and right is 1 and 2. If w

Thought: Take the total assets of each bank as the capacity V of the backpack, and then find the maximum escape rate Initialization: when the robbery amount is 0, it must be safe, so d [0] = 1; other amounts are initially the minimum escape
