@preetesh.magadum Try this:

toNestList = lambda x: x if any(isinstance(i, list) for i in x) else [x]
OUT = []

for i in toNestList(IN[0]):
	if i[0]:
		OUT.append(i)
	else:
		OUT.extend(i)

This is my take on it, but I think Amol’s works as well - might be harder for someone to understand who isn’t familiar with lambda functions. I’m also happy whenever I can find a use for List.Map.
