11th questionsQuestion:Calculate the maximum distance between nodes in a binary tree...If we regard a binary tree as a graph, and the line between parent and child nodes is bidirectional,Let's just define "distance" as the number of edges between

Given a tree composed of n (n Question: This question is completely understandable by People's code...First, find the center of the tree (not the center of gravity). The center is defined as the midpoint of the tree's diameter. If the number of

We know that when calling a function, the computer often uses stacks to store the parameters required for function execution. Because the stack space is limited, the stack in windows is a data structure extended to a low address, is a continuous

There are some rectangles that have the unit weight. To obtain the maximum weight, the rectangle behind the rectangle will overwrite the rectangle above. Question: rectangular cutting. This question is suitable for rectangular cutting, with few

Question: Given a series, move around, and then ask how many columns with prefixes and values greater than or equal to zero.First, follow the general method to copy the sequence, that is, a1a2, ana1a2, and an, and then calculate the prefix and sum.

At first, we thought that the problem could be solved by binary matching, but we had to find the maximum match with both sides, and there was no way to solve it. However, if we think that the maximum stream can solve the problem of binary matching,

I sorted out the classic triangle code circulating on the Internet and added the content I understood. The final goal is to first use try catch blocks in c ++. Then I thoroughly understood the error mechanism of c ++. Here, I would like to share
