Python OPPE 1: September 2024, Set 2 (September 2024 term)

Write a function is_positive_odd_or_negative_even that checks if an integer is either a positive odd number or a negative even number. Return True if the number meets one of these conditions; otherwise, return False.

NOTE: This is a function type question, you don't have to take input or print the output, just have to complete the required function definition.

Example cases

• 0 --> False (neither positive nor negative)
• 3 --> True (positive odd)
• -4 --> True (negative even)
• 4 --> False (positive but even)
• -3 --> False (negative but odd)

Your task

Implement this function:

def is_positive_odd_or_negative_even(n: int) -> bool:

Write the function only — the arguments are read for you and the return value is printed automatically.

Arguments arrive as one Python literal per line, in this order: n.

Example

Input

0

Output

False

Write a function within_and_has_double_quotes that checks if a given string starts and ends with double quotes, and if there are double quotes inside the string (excluding the first and last characters). Return True if both conditions are met, and False otherwise.

NOTE: This is a function type question, you don't have to take input or print the output, just have to complete the required function definition.

Example cases

• "abcd"efgh" --> True (starts and ends with double quotes, and has double quotes inside)
• 'abcd"efgh"' --> False (does not start with double quotes)
• "'abcd'efgh'" --> False (uses single quotes)
• "abcdefgh" --> False (no double quotes inside the quotes)

Your task

Implement this function:

def within_and_has_double_quotes(s: str) -> bool:

Write the function only — the arguments are read for you and the return value is printed automatically.

Arguments arrive as one Python literal per line, in this order: s.

Example

Input

'"abcd"efgh"'

Output

True

Given a tuple t of odd length, and a positive integer n, replace the middle element with n copies of itself.

NOTE: This is a function type question, you don't have to take input or print the output, just have to complete the required function definition.

Examples

For t = (1, 2, 3, 4, 5) and n = 5, the result should be (1, 2, 3, 3, 3, 3, 3, 4, 5).

For t = (1, 2, 3) and n = 4, the result should be (1, 2, 2, 2, 2, 3).

Your task

Implement this function:

def replace_middle_with_n_times_middle(t: tuple, n: int) -> tuple:

Write the function only — the arguments are read for you and the return value is printed automatically.

Arguments arrive as one Python literal per line, in this order: t, n.

Example

Input

(1, 2, 3, 4, 5)
5

Output

(1, 2, 3, 3, 3, 3, 3, 4, 5)
