Tracy is baking some bread! She would like to bake the bread based on the temperature it is outside. There are ~3~ temperature ranges Tracy would like to bake bread in. If the temperature is from ~A~ to ~B~ degrees, Tracy would like to bake pumpernickel. If the temperature is from ~C~ to ~D~ degrees, Tracy would like to bake sourdough. If the temperature is from ~E~ to ~F~ degrees, Tracy would like to bake cornbread. It's guaranteed that the temperature will fall into exactly one of the ranges.

The next line will contain two space-separated integers, ~C~ and ~D (1 \leq C < D \leq 100)~, the temperature range in which Tracy wants to bake sourdough in.

The next line will contain two space-separated integers, ~E~ and ~F (1 \leq E < F \leq 100)~, the temperature range in which Tracy wants to bake cornbread in.

The last line will contain a single integer, ~T (1 \leq T \leq 100)~, the temperature outside.
