A. Broken Clock 题目连接: http://codeforces.com/contest/722/problem/A Description You are given a broken clock. You know, that it is supposed to show time in 12- or 24-hours HH:MM format. In 12-hours format hours change from 1 to 12, while in 24-hours it…
Given a non-empty integer array, find the minimum number of moves required to make all array elements equal, where a move is incrementing a selected element by 1 or decrementing a selected element by 1. You may assume the array's length is at most 10…
Given a non-empty integer array of size n, find the minimum number of moves required to make all array elements equal, where a move is incrementing n - 1 elements by 1. Example: Input: [1,2,3] Output: 3 Explanation: Only three moves are needed (remem…
There are a number of spherical balloons spread in two-dimensional space. For each balloon, provided input is the start and end coordinates of the horizontal diameter. Since it's horizontal, y-coordinates don't matter and hence the x-coordinates of s…

最少知识原则(Least Knowledge Principle),或者称迪米特法则(Law of Demeter),是一种面向对象程序设计的指导原则,它描述了一种保持代码松耦合的策略.其可简单的归纳为: Each unit should have only limited knowledge about other units: only units "closely" related to the current unit. 每个单元对其他单元只拥有有限的知识,只了解与当前单元紧密…
