[杂题撕烤]
T1:给一个长度为n的01串，你需要用K个操作使其全部变成0，每次操作可以对一个区间取反，求方案数（操作顺序不影响方案的不同，不能出现重复操作）。 k,n<=1000
T2:在K维空间中有n个点（xi1,xi2,……,xik），求曼哈顿距离最远的两个点。 K<=8,N<=50000
T3:给出一个长度为n的序列和m个区间[Li,Ri]，分别求这m个区间的最长的无重复数字的子串。N<=200000
T4:给出一个长度为n的序列，问从中选出m个数相乘的第K大。N,K<=10000 m<=13（显然序列里的数有正有负）
T5:一个长度为n的序列，可以在这n个数之间的n-1个位置插入+或*，求所有2^(n-1)的方案的和，而且还可以修改某个数。(n<=500000)
T6:一个无向图，将这个图划分为两个点集，使得两个点集的边权和的差最小。（n<=5000 边权和<=400000）
T7:有n块石头，每块有两个值a[i],b[i]，a[i]表示搬走这块石头所需花费，b[i]表示同时搬走第i和第i-1块石头所需花费，每次询问搬走[l,r]的石头最小花费，并且还有对某块石头的修改操作。（n<=100000）
