write a program that reads in integers separated by a space in one line and displays distinct numbers in their input order and separated by exactly one space (i.e., if a number appears multiple times, it is displayed only once). hint: read all the numbers and store them in list1. create a new list list2. add a number in list1 to list2. if the number is already in the list, ignore it. sample run enter numbers: 1 2 3 2 1 6 3 4 5 2 the distinct numbers are: 1 2 3 6 4 5
