Statistics Calculator!

Write the web app to prompt accepting for positive integers until the user enters a negative integer

• If the entered text is not a positive integer number, then the web app will keep asking for a number until the valid positive integer is entered
• If the entered text is a negative integer, then the web app will show the statistics (average, min, max) of all entered positive integers

Note:

1. You need to implement function to check whether an entered text is a positive interger or not and whether an entered text is a negative interger or not
2. You need to implement function to compute average, min, and max of a list of intergers
