Ask the user to enter an integer between $1$ and $20.$

Use a while loop to calculate the sum of the first $N$ even numbers.

Display the calculated sum.

Inside the while loop, you must also count how many times the loop is executed. Display this count after printing the sum.

Note: Make sure to handle the user input gracefully. If the user enters an invalid number, prompt them to enter again.

Please enter an integer between $1$ and $20$:$0$

$0$ is an invalid input! Please enter an integer between $1$ and $20$: $21$

$21$ is an invalid input! Please enter an integer between $1$ and $20$:$5$

The sum of the first $5$ even numbers is: $20$

The loop executed $5$ times.
