For example, if the array is: [34302, 10078, 34302], it should return true. ic member functions will be called from the provided main program and the answers ese publ rinted ther Th e (see file part2.cpp - do not change the contents of this file) empty file is provided) Item codes are integers Note that item codes can be repeated when scanning .
