Question

Вася запустил программу и получил ошибку. Он подозревает, что где-то не так поставил кавычки. Дана строка в кавычках. Совпадает ли закрывающая кавычка с открывающей? Выведи "ДА" или "НЕТ". Ввод Вывод "Строка" ДА "Данные' НЕТ

Answer 1

n = input()

if n[0] == n[-1]:

print("ДА")

else:

print("НЕТ")

Не знаю, проходили Вы "Срезы" или нет, сделал с ними. Если не проходили, то хотя бы циклы проходили, сделаю с циклом?

Task: Check if the closing quotation mark matches the opening quotation mark in a given string.

To determine if the closing quotation mark matches the opening quotation mark in a given string, we can use a simple algorithm. Here's how we can approach this:

1. Read the input string. 2. Initialize a stack to keep track of opening quotation marks. 3. Iterate through each character in the string. - If the character is an opening quotation mark (single or double), push it onto the stack. - If the character is a closing quotation mark (single or double), check if the stack is empty or if the top of the stack is a matching opening quotation mark. If it is, pop the opening quotation mark from the stack. - If the character is neither an opening nor a closing quotation mark, continue to the next character. 4. After iterating through all the characters, check if the stack is empty. If it is, then the closing quotation mark matches the opening quotation mark. Otherwise, they do not match.

Let's implement this algorithm in Python:

def check_quotation_marks(string):
    stack = []
    opening_quotes = ['"', "'"]
    closing_quotes = ['"', "'"]

for char in string:
        if char in opening_quotes:
            stack.append(char)
        elif char in closing_quotes:
            if len(stack) == 0 or stack[-1] != char:
                return "НЕТ"
            stack.pop()

if len(stack) == 0:
        return "ДА"
    else:
        return "НЕТ"

# Example usage:
input_string = "Строка"
result = check_quotation_marks(input_string)
print(result)

In this example, the input string is "Строка". The function `check_quotation_marks` will return "ДА" because the closing quotation mark matches the opening quotation mark.

Please note that this is a basic implementation and does not account for nested or escaped quotation marks. If you need to handle more complex cases, additional logic may be required.
