Suggest that one metal ball is removed in Newton's cradle. Like the following(thw second one is removed) :

O OOO
Neglect the air resistance~
When we pull one ball(the left hand side one) of it to one side and then release, it will hint the third ball. Compare with the case that the second ball is hinted instead, do the two cases obtain the same result(the last ball move up to the height which is same as the ball pulled at first, total momentum and energy are conserved)?
Help me please...
