题意:输入n,求至少两个正整数,使得这些数的最小公倍数为n且和最小。分析:设n的分解式为,很显然单独作为一项,和最小。这里有两个小技巧:从2开始不断的除n,直到不能整除为止。这样就省去了素数判断的问题,而且缩短了代码量。因为最开始把所有n的2的因数都出去了,后面便不会出现n % 4 == 0的情况,...

依旧是再练习下树状数组的使用:
题目大意: 给出N个数,这些数可以把后面的删掉然后放到最前面形成新的序列
可得到的N种情况,求出这N种情况哪种的逆序数最小
解题思路: 先求出第一个序列的逆序数,然后用很巧妙的办法求下一个序列的逆序数,直到全部求出
序列 4 5 2 1 3 6 ,此序列的逆序数为...
