回文数猜想

Problem Description
一个正整数,如果从左向右读(称之为正序数)和从右向左读(称之为倒序数)是一样的,这样的数就叫回文数。任取一个正整数,如果不是回文数,将该数与他的倒序数相加,若其和不是回文数,则重复上述步骤,一直到获得回文数为止。例如:68变成154(68+86),再变成605(154+451),最后变成+506),而1111是回文数。于是有数学家提出一个猜想:不论开始是什么正整数,在经过有限次正序数和倒序数相加的步骤后,都会得到一个回文数。至今为止还不知道这个猜想是对还是错。现在请你编程序验证之。
每行一个正整数。
特别说明:输入的数据保证中间结果小于2^31。
对应每个输入,输出两行,一行是变换的次数,一行是变换的过程。

Yup!! The problem nam just add a set of numbers. But you may feel yourselves condescended, to write a C/C++ program just to add a set of numbers. Such a problem will simply question your erudition. So, let’s add some flavor of ingenuity
Addition operation requires cost now, and the cost is the summation of those two to be added. So, to add&1&and&10, you need a cost of11.&If you want to add&1,&2&and&3.&There
are several ways C
1 + 2 = 3, cost = 3
3 + 3 = 6, cost = 6
1 + 3 = 4, cost = 4
2 + 4 = 6, cost = 6
Total = 10
2 + 3 = 5, cost = 5
1 + 5 = 6, cost = 6
Total = 11
I hope you have understood already your mission, to add a set of integers so that the cost is minimal.
Each test case will start with a positive number,&N (2 ≤ N ≤ 5000)&followed by&N&positive integers (all are less than&100000). Input is terminated by a case where the value of&N&is zero.
This case should not be processed.
For each case print the minimum total cost of addition in a single line.

Problem Description
News comes!~City W will be rebuilt with the expectation to become a center city. There are some villages and roads in the city now, however. In order to make the city better, some new villages should be built and some old ones should be destroyed. Then the
officers have to make a new plan, now you , as the designer, have the task to judge if the plan is practical, which means there are roads(direct or indirect) between every two villages(of course the village has not be destroyed), if the plan is available,
please output the minimum cost, or output&what a pity!&.
Input contains an integer T in the first line, which means there are T cases, and then T lines follow.
Each case contains three parts. The first part contains two integers l(0&l&100), e1, representing the original number of villages and roads between villages(the range of village is from 0 to l-1), then follows e1 lines, each line contains three integers a,
b, c (0&=a, b&l, 0&=c&=1000), a, b indicating the village numbers and c indicating the road cost of village a and village b . The second part first contains an integer n(0&n&100), e2, representing the number of new villages and roads(the range of village is
from l to l+n-1), then follows e2 lines, each line contains three integers x, y, z (0&=x, y&l+n, 0&=z&=1000), x, y indicating the village numbers and z indicating the road cost of village x and village y. The third part contains an integer m(0&m&l+n), representing
the number of deserted villages, next line comes m integers, p1,p2,…,pm,(0&=p1,p2,…,pm&l+n) indicating the village number.&
Pay attention: if one village is deserted, the roads connected are deserted, too.
For each test case, If all villages can connect with each other(direct or indirect), output the minimum cost, or output &what a pity!&.

有若干组,每组输入有2行,第一行整数N表示有N个密文,接着一行有N个整数分别表示N个密文。
输出仅有大写字母组成的原文。

C语言中 (!a&b&&b!=c||x+y&=3是什么意思
这是一个bool表达式,分为3部分1、!a&b 就是判断!a与b的大小,a是布尔类型的,将a转化成数值型和b比较,若!a大于b则表达式为true,否则表达式为false2、b!=c 就是判断b与c的值是否相等,若相等表达式为false,否则表达式为true3、 x+y&=3 判断x+y与3的值的大小,若x+y&=3则表达式为true,否则为false 这个bool表达式的值由这3部分决定,先进行&&再进行||,按顺序进行

x+y&=3 !a&b 就是 非a小于b啊,目测a是布尔类型的,强制转化成数值型和b比较b!=c 和x+y&=3很简单,就不说了
IF(!a&b&&b!=c||x+y&=3) {
……}1.(!a&b)的 等同条件是 “a&=b”
,请想想 “!”
这个符号的作用。2.b!=c :b不等于c3.x+y&=3
: x+y小于等于34.(!a&b&&b!=c||x+y&=3)
-& (A || B)
( (!a&b&&b!=c) || (x+y&=3) )----&----& A或者B的条件满足,能进入IF{}语句,A且B两者条件都不满足,不能进入IF{}语句。

C语言的一个问题
main(){int a=5,b=4,c=3,d=2;if(a&b&c);其中的a&b&c为什么是假的呢?if((c-1&=d)==1)为什么会是真的呢?
提问者采纳
因为C++不支持连续比较你要是需要表达a&b&c就要写成a&b&&b&c的形式否则他会从左到右一个表达式一个表达式求值a&b&c= (a&b)&c如果a&b 则表达式a&b值为1如果1&c则表达式(a&b)&c为1这样求的第二个同理先对表达式求值c-1&=d因为 c-1=2d=2所以这个式子成立那么这个式子的值就是1所以(c-1&=d)==1为真

是这样执行的
==& 变为1&c
1&3 为假 c-1=2&=d 为真 值为 1 1==1 为真
是这样的你可以这样看if(a&b&c) -& if((a&b)&c)由于a&b本身是一个BOOL值,此时为1,所以.....,应该清楚了吧.同理 (c-1&=d)也是一个BOOL值
a&b为真,就是1.1&c=3 当然就为假啦c-1=2,d=22=2就为真
