complete the following reactions with appropriate structures of products?

C6H5CH=CH2 --Br2 [A] -- i)NaNH2 ii)CH3I[B]

please tell the reason also

The reaction sequence is shown below.The 1 step is simple addition of Br2 across double bond.In 2 nd step there are 2 parts.
At first dehalogenation in presence of NaNH2 to form alkyne. Then removal of acetic H of alkyne with NaNH2 and attack of CH3I to give the desired product.Both the intermediate step is shown below.
