Runtime error is because you are calling for v.back() for else if part, and initially for this case, v is empty. So this will produce a runtime error.
can u please give me some test cases along with their answer cause i cant understand the qn completely
this is my code it works fine but the only problem is that how do i give the answer after calculating n.o of u know the places left that will be fulfilled by the string a and b

Some cases i can think of are:
4 2
((
answer is 1 as only answer possible is (())
6 4
)()(
answer is 1 again and only answer possible is ()()()
6 2
((
answer is 3. (())(), ((())) and ()(()).
6 2
))
Your code’s output: 2
Expected Output: 3.
5 2

Your code’s output: 2
Expected Output: 0
