Repeated elements in an array

if I have:
A=[3 7 25 27 30 31 32 34 35 36]
B=[2 4 2 2 2 0 3 2 3 2]
How can I have the index of the first element repeated in B and use it in A to have :
A=[3 7 25 31 32 34 35 36]
B=[2 4 2 0 3 2 3 2]
I used diff(B), but it will give:
A=[3 7 30 31 32 34 35 36]
B=[2 4 2 0 3 2 3 2]
(30 instead of 25, 30 represents the last element in B that has value of 2; or what I want is the first element in B that has value of 2 which is 25 in my case).
Is there any logic way or i should use a loop?
