The general solution to this problem is to combine the features of the root of each layer of the Binary Tree by sorting the first number in the first order, divide the first string in the middle order into two parts, the left tree on the left, the

DP [1] [0] = 0; for (I = 3; I

# Include int F1 [555], F2 [555], F3 [555]; void sum () {int I; for (I = 1; I = 1; I --) printf ("% d", F3 [I]); printf ("\ n ");} return 0 ;}

In this way, the topological sorting of water will time out, cry, and the variables defined in it will actually time out. It's right to take it out, and, the sentence must be harsh! Description There are n game teams (1 Program Determine the

Classic search question. Write a DFS non-Recursive Implementation. Actually, Recursive Implementation is more scientific. BFS functions are also better. It is mainly convenient to return, and recursion is convenient to enter. In all, it is a

# Include void quick_sort (INT s [], int L, int R) {If (L = x) // you can find a number smaller than X on the left, if less than X, stop j --; if (I J. Therefore, a large loop is displayed, and the value of S [I] = x is directly assigned; while

This is a standard topic of topsort, that is, the judgment ring, and there are still situations where there are insufficient conditions. It is better to clarify the train of thought. I won't be able to do it at the beginning, I learned the code of

If a graph is created in the forward order, first 1 is output, and then 2 is updated to 0. Therefore, 2 is output, which is inconsistent with the meaning of the question, because 1 and 5 have the same priority, if the order of 2, 5 is different,
