      Ope[p][0]=x;
      Ope[p][1]=y;
    
  }

  for (int q=0; q<N;q++ ){
      A[q]=0;
  }
  for (int e=0;e<M;e++){
      for (int w=1;w<N+1;w++){
          if(w % Ope[e][1] != 0 && A[w-1]==0){
              A[w-1]=Ope[e][0];
              sum += Ope[e][0];
          }

Which Problem are you trying to solve?
