Online GDB. Pythоn Online. Questiоn: Write а functiоn isStringUnique(text) thаt tаkes a string as input. A string is considered unique if each character occurs only once. If any character occurs two times or more, then the string is not unique. The function should return True if the string is unique, and False if any character is repeated. Assume that text string input will all be in lowercase. You must NOT use .find(), .count(), list comprehension, or data structures (sets and dictionaries) Examples isStringUnique("cat") should return True (because all characters appear only once)isStringUnique("letter") should return False (because the letter "t" appears twice)isStringUnique("moon") should return False (because the letter "o" appears twice)isStringUnique("python") should return True (because all characters appear only once)isStringUnique("abcabc") should return False (because the letters "a", "b", and "c" each appear twice)
