However, it is not in relation to the dictatorship of Primo de Rivera, but
to the emerging Catalan politics of the time that FC Barcelona can arguably
be said to have held the most institutional significance. The prologue to
the official history of the club claims that “throughout the most difficult
times [FC Barcelona] was the standard that represented Catalonia and the
Catalan people’s desire for freedom” (FC Barcelona: 2011). These political
linkages, as I hope to demonstrate, seemed to grow ... 阅读全帖

这一段开头满难,我先翻了后面几段,xq先看看:
If we apply this strand of thinking to the situation at FC Barcelona in the
aftermath of the fall of the Primo de Rivera regime, then the club takes on
greater political significance. While the club itself may not have been
founded along political lines, it originally defined itself as “apolitical
but always prepared to stand up for the human rights of Catalans” (Burns:
1999, p.100), but the individuals guiding it seemed to behave in an
increasingly politically aware fash... 阅读全帖

The first linkages made between FC Barcelona and political action came in
June 1925 during a benefit match at the club’s Les Corts ground (Ball: 2003
, p.92-93). With Primo de Rivera having outlawed both regional government
and use of the Catalan language in the preceding months, the game was seen
as a political opportunity for the people of Barcelona, Francesc Cambo and
Joaquin Ventosa Calvell – two high-profile Catalan politicians – both
being in attendance (Burns: 1999, p.86-87).

The army of General Franco had marched into the city of Barcelona on 26th
January 1939, the civil war reaching its official conclusion shortly
afterwards (Goldblatt: 2006, p.303). The fall of the city seemed to neuter
FC Barcelona’s direct political significance, the new regime clearly
viewing the club as an instrument of regional autonomy which needed to be
silenced (Goldblatt: 2006, p.305). Indeed, Franco hoped to humiliate the

There are only 5 different kinds of expressions with different arrangement
of parenthesis for 4 numbers (using an example of 1,2,3,4), shown as below:
1) ((1 + 2) + (3 + 4))
2) (((1 + 2) + 3) + 4)
3) ((1 + (2 + 3)) + 4)
4) (1 + ((2 + 3) + 4))
5) (1 + (2 + (3 + 4)))
An easy way is to brute force using recursive method. Choose all possible
neighboring pairs and merge them using the operators (add, subtract...). For

前天在版上看到打印所有矩阵结合次序(Catalan Numbers)的讨论,最后给出的程序比

可以变形成矩阵结合次序。

来自主题: JobHunting版 - 我来出个题吧
第二题就基本dfs吧,空间肯定不可能常数(如果stack space也算空间的话)。为什么
呢?
因为所有长度为n的嵌套正确的括号串的总数就是第 n/2 个 catalan number 。
给个例子,n=6 的时候,需要打印的总数是第 3 个 catalan number = C3 = 5.
当 n = 30, 需要打印的个数是 C15 = 9694845 个。
所以空间耗费肯定不可能常数。DFS 递归程序不是 tail-recursive,所以转换成非递
归不是那么直接。如果硬要转换的话,那也得用stack来模拟DFS,也是一样要耗空间。
最直接的程序(也应该是最简洁的)就是数,‘(’+1,‘)’就 -1,任何时候 < 0
就停止递归。
利用 n = 30 代入函数,
./a.out 14.87s user
可以做适当优化来剪枝(程序也没那么复杂),
./a.out 1.79s user

它说明对于任何ε>0,存在常数Cε> 0,并对于任何三个满足a+ b= c及a,b互质的正整
数a,b,c,有:

rad(n)在此表示n的质因数的积。[1]
截止2005年,此猜想仍未证明,却衍生一BOINC项目名为“ABC@Home”。
1996年,爱伦·贝克提出一个较为精确的猜想,将rad(abc)用
