# Python critical bug message from dmitrygenius6@gmail.com
# Nested "while" cycles works in the incorrect way.
#
# Next short example prove it. It must prints all pairs from (0,0) to (999,999)
# But due to error in the interpreter it prints only (0,0) -> (0,999)
# Error appears in 2.6, 2.7.1, 3.2 version.
