当我尝试通过发出命令“ g ++ qr.cpp -o qr”来编译此文件时,系统挂起。我在其他任何地方都没有看到这种错误。
#include<iostream> using namespace std; bool win[1000000001]; bool know[1000000001]; int sixes[] = {6, 36, 216, 1296, 7776, 46656, 279936, 1679616, 10077696, 60466176, 362797056}; bool check(int n){ cout << n << endl; if(!know[n]){ bool b = check(n-1); for(int i=0; i<11; i++){ if(n > sixes[i]){ b = b & check(n-sixes[i]); } } win[n] = !b; } return win[n]; } int main(){ win[1] = know[1] = true; for(int j=0; j<11; j++){ win[sixes[j]] = know[sixes[j]] = true; } int n = 1; cin >> n; int i = 0; while(n != 0){ i++; win[n] = check(n); cout << i << (win[n]?"-Heckle":"-Jeckle"); cin >> n; if(n!=0) cout << endl; } return 0; }
我的编译器版本信息如下。

你知道这些有多大吗?
bool win[1000000001]; bool know[1000000001];
每个至少1GB !!!您将要动态分配它们…
