I have problem with problem 3C. This is my submisson:139851350 Source code:#include using namespace std; class chess{ public: int cnt0,cntx; int chs[3][3]; }; give(chess c){ string str[3]; cin>>str[0]>>str[1]>>str[2]; for(int i=0;i<3;i++){ for(int j=0;j<3;j++){ if(str[i][j]=='.'){ c.chs[i][j]=0; } if(str[i][j]=='0'){ c.chs[i][j]=1; c.cnt0++; } if(str[i][j]=='X'){ c.chs[i][j]=2; c.cntx++; } } } } bool win(chess c,int num){ bool acr=false; for(int i=0;i<3;i++){ bool acr_=true; for(int j=0;j<3;j++){ acr_=acr_&&(c.chs[i][j]==num); } acr=acr||acr_; } bool dow=false; for(int i=0;i<3;i++){ bool dow_=true; for(int j=0;j<3;j++){ dow_=dow_&&(c.chs[j][i]==num); } dow=dow||dow_; } bool bl=false;//0 0 0 bool bl0=true;//0 0 0 bool bl1=true;//0 0 0 for(int i=0;i<3;i++){ bl0=bl0&&c.chs[i][i]==num; bl1=bl1&&c.chs[i][2-i]==num; } bl=bl||bl0; bl=bl||bl1; bool result=bl||dow; result=bl||acr; return result; } bool isillegal(chess c){ int X0=c.cntx-c.cnt0; if(X0<0||X0>1){ return false; } if(win(c,1)&&win(c,2)){ return false; } if(win(c,1)&&c.cntx>c.cnt0){ return false; } if(win(c,2)&&c.cntx==c.cnt0){ return false; } return true; } bool isdraw(chess c){ int cntused=c.cnt0+c.cntx; if(cntused==9&&!win(c,1)&&!win(c,2)){ return true; } return false; } void solve(){ chess c; give(c); bool win0=win(c,1); bool winx=win(c,2); bool illc=isillegal(c); bool draw=isdraw(c); bool nextx=c.cnt0==c.cntx; if(illc){cout<<"illegal";return;} if(win0){cout<<"the second player won";return;} if(winx){cout<<"the first player won";return;} if(draw){cout<<"draw";return;} if(nextx){cout<<"first";return;} cout<<"second"; } int main(){ solve(); return 0; }

And its exit code is 2147483647! I tried many times. Please help me!
