We worked our way up to logic gate implementations for half adders and full adders, as illustrated below. In closing, I asked you to start thinking about how we could use these functions to add two ...

1. DFS using depth marker: 每个depth都存一下。然后如果有不符合条件的，存为-1. 一旦有 <0 或者差值大于1， 就全部返回Integer.MIN ...

Abstract: For increasingly complex real-world optimization problems, a large number of researches have shown that differential evolution (DE) is an effective problem-solving algorithm. Despite its ...

2. Only calculate depth using maxDepth function. Same concept as in 1, but cost more traversal efforts. Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced ...
