ACM 数论 Interesting Integers

题目： Undoubtedly you know of the Fibonacci numbers. Starting with F_1 = 1F1=1 and F_2 = 1F2=1,every next number is the sum of the two previous ones. This results in the sequence 1, 1, 2, 3, 5, 8

Codeforces Round #725 (Div. 3)-F. Interesting Function

题目链接 You are given two integers l and r, where l<r. We will add 1 to l until the result is equal to r. Thus, there will be exactly r−l additions performed. For each such addition, let’s look at the nu

J - Scarily interesting!

题意：两个队进行比赛，每个队n个人，现在已知每个人会得多少分。每个人的得分不超过6。比赛进行n回合，每个回合一个队派一个人参赛，每个人只能参赛一次。一个队伍前i个回合的总得分为该队伍派出的前i个人的得分和。现在让你输出一个方案，让比赛尽量不失去悬念。假设第i回合比赛已经没有悬念，那么我们需要输出一个方案，让i尽量的大。思路：一看就是贪心题，哎，贪心思路不对，我和队友把它按照先输出相同的

shuoj-1942: yaoge and xyiyy's interesting game-数学-快速幂

Description xyiyy和yaoge正在做一个游戏。现在yaoge面临这游戏中关键的一步，如果不能算出这个结果，那么他将要付出一块鸡排的代价。现在yaoge有两个数A和B，yaoge对这两个数进行k次操作，每次操作定义如下：若A≤B，则B = B - A，A = A + A 若A>B，则A = A - B，B = B + B 现要求求出k次操作之后较小的那个数的值 Inpu

HDU 2426 Interesting Housing Problem 最小费用最大流 or KM算法

这道题貌似是08年杭州网络赛的题目，看完题后就发现是个最优匹配问题，用KM或者最小费用最大流做，就找了个最小费用最大流的模板，改了一下，就能过了、建图还是比较好想的，建立一个超级源点，一个超级汇点，然后源点与学生连边，流量限制为1，费用为0，汇点与房间连边，流量限制为1，费用为0，然后学生与房间之间的边，流量限制是1，费用就是题目给的喜好值了，注意，每次加边，都要加一个相应的反向边，

1200*B. Interesting Subarray（贪心规律）

Problem - 1270B - Codeforces 解析：可以发现，对于某个符合条件的数列，如果两个最值不在两端，那么可以删去两端多余的元素直到两个最值在两端为止。我们观察某两个相邻元素a、b，可以发现这两个元素组成的序列成立的条件为abs(b-a)>=2 再观察三个元素a、b、c，可以发现成立条件为abs(c-a)>=3
