In PYTHON, write a code that allows the user to input two non-negative number sequences in increasing order (the numbers entered are always getting bigger, and no number repeats), both terminated by a -1.

The output of this code should be a third sequence that is a COMBINATION of both sequences 1 and 2 and is sorted in non-decreasing order where if there are two of the same number they are put together in the final sequence.

Please do this using PYTHON, only using 3  SEPARATE WHILE LOOPS! NO language of "break", "len", "True", or "return" anywhere in the code!
