SUMMARY문자열에서 중복되는 문자없이 유일한 문자들만 존재하는지 판별하는 함수를 만들어보자. Code# unique_str.py def unique_string(str): if len(str) > 256: return False hash = [False] * 256 for ch in str: if hash[ord(ch)] is True: return False else: hash[ord(ch)] = True return True print('문자열을 입력하세요.') str = input() print(unique_string(str))

SUMMARYpython에서 문자열을 뒤집는 함수를 만들어보자. Code# reverse_str.py # solve_1 def reverse_string(str): return str[::-1] # solve_2 def reverse_stack(str): stack = [] for ch in str: stack.append(ch) result = "" while len(stack) > 0: result += stack.pop() return result print('뒤집을 문자열을 입력하세요.') str = input() print(reverse_stack(str))
