With India 405 for 4, I think we can turn our attention, for a few moments to this Report we're writing. Now what I've put up on the word processor is the text of The report of the transbinary working group on agriculture (September 1984). If we just scroll through it, perhaps ...
binary works by using combinations of ones and zeros to represent different values. each one or zero is referred to as a "bit", and each combination of bits creates a "binary code". this binary code can represent any number, character, data type, or instruction that a computer can use....

LeetCode: 98. Validate Binary Search Tree 题目描述 Given a binary tree, determine if it is a valid binary search tree (BST). Assume a BST is defined as follows: The left subtree of a node contains only nodes with keys less than the node’s key. ...
The main object studied in this book is a (binary) code. A binary code of length n is simply a nonempty set of binary vectors of length n. More generally, we have the following definition. Definition 2.1.1 Let Q be a finite set with q elements. A nonempty subset C of Qn = Q× ...
