substring("0123456789", 0, 5)
# result = "01234"

substring("0123456789", 2, 5)
# result = "234"

substring("0123456789", -20, 5) # startPos < 0
# result = "01234"

substring("0123456789", 0, 20)	# endPos >= len(inputString)
# result = "0123456789"

substring("0123456789", 5, 0)	# startPos >= endPos
# result = ""
