Change the element of the vector with respect to the element of the direction vector

If the element of the direction vector is 2, then the new element of the vector is two times the corresponding element in the vector.

If the element of the direction vector is 1, then the new element of the vector is two times the corresponding element in the vector minus one.

Attention: 'if' can not be used

Example

 direction vector d = [1  2  2  2  1  2  1  2]
 vector =             [1  2  3  4  5  6  7  8]
 new_vector =         [1  4  6  8  9 12 13 16]
