Thebinary conversionof 7 is (111)2, but the same number is represented in Binary Coded Decimal system in four bit form as (0111). Also, the numbers from 0 to 9 are represented in the same way as in binary system but after 9 the representation in BCD are different. For example, the...

ASCII (American Standard Code for Information Interchange) is a 7-bit characters code, with values from 0 to 127. The ASCII code is a subset of UTF-8 code. The ASCII code includes control characters and printable characters: digits, uppercase letters and lowercase letters. ...
Given a binary tree, find its minimum depth. The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node. 题解:注意没有的分支不算。 /** * Definition for a binary tree node. ...
