Given no of weeks. Write a program to convert weeks to days.

Examples:

Input: weeks = 4
Output: 28 days

Input: weeks = 2
Output: 14 days

Approach: To solve the problem, follow the below idea:

Since we know a week has 7 days. So, to find no of days in a week, we multiply weeks by 7.

1 week = 7 days
n weeks = n*7 days

Below is the implementation of the above approach:

9 weeks is equal to 63 days.

Time Complexity: O(1)
