Describe
Professor Q develops a new software. The software consists of n modules which is numbered from 1 to N. The i-th module would be started up by signal Si. If signal Si is generated multiple times, the I-th module'll also be started multiple times. The modules different is started up by the same signal. During its lifecircle, the i-th module would generate Ki signals:e1, E2, ..., EKi. These signals may, start up, modules and so on. Fortunately the software is so carefully designed that there are no loop in the starting chain of modules, which means even Tually all the modules would be stoped. Professor Q generates some initial signals and want to know what many times each module is started.

Input
The first line contains an integer T, the number of test cases. T test cases follows.

For each test case, the first line contains contains, numbers N and M, indicating the number of modules and number of S Ignals that Professor Q generates initially.

The second line contains M integers, indicating the signals that Professor Q generates initially.

Line 3~n + 2, each line describes an module, following the format S, K, E1, E2, ..., EK. S represents the signal that is the start up this module. K represents the total amount of signals that is generated during the lifecircle of this module. and E1 ... EK is these signals.

For 20% data, all N, M <= 10
For 40% data, all N, M <= 103
For 100% data, all 1 <= T <= 5, N, M <=, 0 <= K <= 3, 0 <= S, E <= 105.

Hint:huge input in this problem. Fast IO such as scanf and BufferedReader are recommended.

Output
For each test case, the output a line with N numbers Ans1, Ans2, ..., ansn. Ansi is the number of the Times, the I-th module is started. In case the answers is too large, output the answers modulo 142857 (the remainder of division by 142857).

    • Method one: Using the stack for processing, the method is simple logic, easy to write code
#include <vector>#include <stack>#include <iostream>using namespace STD;voidFind (int* * A,intLenintB vector<int>& next);intMain () {intT =0;intN =0, M =0;Cin>> T; for(inti =0; i < T; ++i) {//N:module num; M:init Num        Cin>> N >> M;//Get the init        int* init =New intM (); for(intj =0; J < M; ++J)Cin>> Init[j];//Get the modules        int* * Mods =New int*[n]; for(intj =0; J < N; ++J) {intModid =0, Childnum =0;Cin>> Modid >> Childnum; MODS[J] =New int[Childnum +2](); mods[j][0] = Modid; mods[j][1] = Childnum; for(intK =0; K < Childnum; ++K)Cin>> mods[j][k+2]; }int* CNT =New intN (); Stack<int>S vector<int>Next for(intj =0; J < M; ++J) S.push (Init[j]); while(!s.empty ())            {next.clear ();            Find (mods, N, S.top (), next); S.pop (); for( vector<int>:: Iterator iter = Next.begin (); Iter! = Next.end (); ++iter) {cnt[*iter]++; for(intj =0; J < mods[*iter][1]; ++J) S.push (mods[*iter][2+J]); }        } for(intj =0; J < N; ++J)cout<< Cnt[j] <<" ";cout<< Endl;//Release memory        Delete[] init; for(intj =0; J < N; ++J)Delete[] mods[j];Delete[] CNT; }}voidFind (int* * A,intLenintB vector<int>& Next) { for(inti =0; i < Len; ++i) {if(b = = a[i][0]) Next.push_back (i); }}
    • Method Two: The simplest and most straightforward method of finding, this requires the code to be careful not to handle errors.
#include <vector>#include <iostream>using namespace STD;voidGet (int* * A,intLenintLineint* CNT);voidFind (int* * A,intLenintB vector<int>& next);intMain () {intT =0;intN =0, M =0;Cin>> T; for(inti =0; i < T; ++i) {//N:module num; M:init Num        Cin>> N >> M;//Get the init        int* init =New intM (); for(intj =0; J < M; ++J)Cin>> Init[j];//Get the modules        int* * Mods =New int*[n]; for(intj =0; J < N; ++J) {intModid =0, Childnum =0;Cin>> Modid >> Childnum; MODS[J] =New int[Childnum +2](); mods[j][0] = Modid; mods[j][1] = Childnum; for(intK =0; K < Childnum; ++K)Cin>> mods[j][k+2]; }int* CNT =New intN (); for(intj =0; J < M; ++J) { vector<int>Next Find (mods, N, Init[j], next); for( vector<int>:: Iterator iter = Next.begin (); Iter! = Next.end ();                    ++iter) {cnt[*iter]++;            Get (mods, N, *iter, CNT); }        } for(intj =0; J < N; ++J)cout<< Cnt[j] <<" ";cout<< Endl; }}voidGet (int* * A,intLenintLineint* cnt) { for(inti =0; I < a[line][1]; ++i) { vector<int>Next Find (A, Len, a[line][i+2], next); for( vector<int>:: Iterator iter = Next.begin (); Iter! = Next.end ();            ++iter) {cnt[*iter]++;        Get (A, Len, *iter, CNT); }    }}voidFind (int* * A,intLenintB vector<int>& Next) { for(inti =0; i < Len; ++i) {if(b = = a[i][0]) Next.push_back (i); }}
