Seal the matrix

[programmer0]

i have to seal the matrix starting from the row where the sum of the elements is an even number

  for(i=0;i<n;i++)
	{
		s=0; for(j=0;j<k;j++) s+=p[i][j];
		if(s%2==0) { delete[] p[i]; p[i]=NULL;
			for(m=i;m<n-1;m++) p[m]=p[m+1]; n--; break; }
	}

do i have to white p[i]=NULL after deleting it?

Try getting in contact with Neo, he knows a lot about the matrix. To my knowledge, you do not have to set it to NULL.
