Interview Question: combine two vectors as third vector with no repeatation of duplicate elements and without using collection framework methods

package

/*

* Vector v1 and V2 contain some common objects

* Create vector V3 which will contain all V1 and V2

* and common objects only once

* without using colletion framework functions
