In this problem, you will create a program that reads an integer (1–7), determines the corresponding day of the week using a switch statement, and displays the result to standard output.

Input Format

One line contains an integer from 1 to 7, or an integer outside the range.

Output Format

Output the day of the week judged using a switch statement.

• 1: "Monday"
• 2: "Tuesday"
• 3: "Wednesday"
• 4: "Thursday"
• 5: "Friday"
• 6: "Saturday"
• 7: "Sunday"
• Others: "Invalid day"

Constraints

• Input is an integer

Key Points

• Switch statements are convenient when checking equality against multiple values
• Don't forget to write break statements at the end of each case label
• Handle out-of-range values with the default case
