Triple 构造
题目大意:给定n,要求构造三个0~n−1的排列A,B,C,使得对于任意i(i∈[0,n−1])满足Ai+Bi≡Ci(mod n)首先我们来考虑n是奇数的情况。以n=7为例A 0 1 2 3 4 5 6B 6 4 2 0 5 3 1C 6 5 4 3 2 1 0看出来怎么构造的了么?没错,排列A每次+1,排列B每次−2,排列C每次−1由于n是奇数,这样可以保证A,B,C三个排列都不重复那么n是偶数的

(组合数学)
题意:要求你求出字典序比当前序列小的序列的逆序数的和。解析:组合数学的问题,这题先要求出n个数的全排列的逆序数的和是多少。当n=1,他只有1个排列,然我们现在利用1推出2的组合是多少。思路是把2往前面1排好的序列内插入,显然也可以插前面和后面。那么会产生12、21这两个排列,由于2是最大的数,所以当插入后面的位置时产生的逆序对多0,插在前面的位置逆序对多1,那么2种插法总共会多出1个逆序数对。而1
