	...
	...
	companion object {
	fun newInstance() : ExampleFragment {
	return ExampleFragment()
	}
	}
	}

	def toStr(list):
	return ''.join(list)

	def permute(s, l, r):
	"""
	Function to find permutations of a given sting
	:arg s : string,
	:arg l : left element of the string,
	:arg r : right element of the string.
	"""

	# python program to print below average marks
	marks = [100, 76, 45, 28, 52, 17, 83]
