如果(a,b,c)也相等 则说明两直线重合 也就是说 先把所有平行及重合的抛去 然后再加上重合的组数 就是最后结果 代码如下:(学长的代码) #include<bits/stdc++.h>#definell long long#defineinf 0x3f3f3f3f#definems(x,a) memset(x,a,sizeof(x))#definevc vector#definep
The first line of the input contains an integerT(1≤T≤1000) , denoting the number of test cases. In each test case, there is one integern(1≤n≤100000) in the first line, denoting the number of lines. For the nextn lines, each line contains four integersxai,yai,xbi,ybi(|xai|,...

Since the occurrence of symmetry-breaking-induced thresholds on all scales is an essential ingredient for the corresponding RG flows, the standard reasoning used for the DER and implying one-loop universality is no longer applicable. This raises naturally the question of scheme dependence: is the ex...
