1001-I Count Two Three

题意：给出一个整数n, 找出一个大于等于n的最小整数m, 使得m可以表示为2a3b5c7d。

分析：很好想，因为数据是在1~1e9之间的，所以直接将所有2a3b5c7d的形式且小于1e9的数字打表，然后二分搜索出大于等于n的最小整数。

1002-Cure

题意：给n，求 ∑nk=11k2，精确到五位小数。

分析：根据百度很快就可以查到当n无限大的时候，表达式无限接近于π26。那么我考虑在精度为五位小数的情况下，前面若干答案是会改变的，但是到一定程度之后答案将会不变。

1004-Tea

题意：有一壶水, 体积在 L 和 R 之间, 有两个杯子, 你要把水倒到两个杯子里面, 使得杯子水体积几乎相同(体积的差值小于等于1), 并且使得壶里剩下水体积不大于1. 你无法测量壶里剩下水的体积, 问最小需要倒水的次数。

分析：这道题目就是想的特别麻烦，但是如果思路搞清楚了，那么还是很简单的（最重要的是思考的全面性，无重复无遗漏）。开始看着这道题的时候最好不要考虑特殊的情况（不然的话，很容易的会被这些特殊的情况给搞混的），不妨将L和R取成两个本身很大而且相差很大的数。对于最小的数L，我们很容易想到在第一个水杯中倒入L2，那么在第二个水杯中就可以最多倒下L2+1的水量，相当于前面L~L+1的水量就不需要考虑了。但是重新考虑，这样的开始方法就相当于浪费了前面的L2−0.5~L2的水量，这半部分的比较就没有了，不是最完美的倒水方法。考虑方法二，开始给第一个杯子倒L2+0.5的水量，壶中剩下的水量就是L2−0.5~的水量，这样的话，L2−0.5~L2+1.5的水量就都不用考虑了，相当于前面L~L+2的水量就都不用考虑了。仔细考虑，L2−0.5~L2+2.5的水量都可以用2次操作来完成。之后在第二个水杯里面倒入L2+1.5的水，剩下的考虑是否需要倒入第一个杯子（如果小于1的话留在壶中），而且每次倒入2水量的水是最合理、最快的。

前面讲的是非特殊情况的倒法。我觉得想的话，比较难的是想出倒水的方法，一般人都是第一种方法居多，这样的话规律可能就错了。比赛的时候还是多写出几组数据，然后测试比较好。

对于特殊数据，无非就是L==R或者L==0或者L==1之类的。考虑全面了，基本就AC了。

XJB补，算是补完了，还有一个大连赛区就告一段落了。然后，就是正式赛，希望我能在正式赛上面拿到牌牌把。

1001-I Count Two Three

题意：给出一个整数n, 找出一个大于等于n的最小整数m, 使得m可以表示为2a3b5c7d。

分析：很好想，因为数据是在1~1e9之间的，所以直接将所有2a3b5c7d的形式且小于1e9的数字打表，然后二分搜索出大于等于n的最小整数。

1002-Cure

题意：给n，求 ∑nk=11k2，精确到五位小数。

分析：根据百度很快就可以查到当n无限大的时候，表达式无限接近于π26。那么我考虑在精度为五位小数的情况下，前面若干答案是会改变的，但是到一定程度之后答案将会不变。

1004-Tea

题意：有一壶水, 体积在 L 和 R 之间, 有两个杯子, 你要把水倒到两个杯子里面, 使得杯子水体积几乎相同(体积的差值小于等于1), 并且使得壶里剩下水体积不大于1. 你无法测量壶里剩下水的体积, 问最小需要倒水的次数。

分析：这道题目就是想的特别麻烦，但是如果思路搞清楚了，那么还是很简单的（最重要的是思考的全面性，无重复无遗漏）。开始看着这道题的时候最好不要考虑特殊的情况（不然的话，很容易的会被这些特殊的情况给搞混的），不妨将L和R取成两个本身很大而且相差很大的数。对于最小的数L，我们很容易想到在第一个水杯中倒入L2，那么在第二个水杯中就可以最多倒下L2+1的水量，相当于前面L~L+1的水量就不需要考虑了。但是重新考虑，这样的开始方法就相当于浪费了前面的L2−0.5~L2的水量，这半部分的比较就没有了，不是最完美的倒水方法。考虑方法二，开始给第一个杯子倒L2+0.5的水量，壶中剩下的水量就是L2−0.5~的水量，这样的话，L2−0.5~L2+1.5的水量就都不用考虑了，相当于前面L~L+2的水量就都不用考虑了。仔细考虑，L2−0.5~L2+2.5的水量都可以用2次操作来完成。之后在第二个水杯里面倒入L2+1.5的水，剩下的考虑是否需要倒入第一个杯子（如果小于1的话留在壶中），而且每次倒入2水量的水是最合理、最快的。

前面讲的是非特殊情况的倒法。我觉得想的话，比较难的是想出倒水的方法，一般人都是第一种方法居多，这样的话规律可能就错了。比赛的时候还是多写出几组数据，然后测试比较好。

对于特殊数据，无非就是L==R或者L==0或者L==1之类的。考虑全面了，基本就AC了。

XJB补，算是补完了，还有一个大连赛区就告一段落了。然后，就是正式赛，希望我能在正式赛上面拿到牌牌把。
