I got lots of files beginning like this:

Program title: Primes
Author: Kern
Corporation: Gold
Phone: +1-503-555-0091
Date: Tues April 9, 2005
Version: 6.7
Level: Alpha

Here we will work with strings like the string data above and not with files.

The function change(s, prog, version) given:

s=data, prog="Ladder" , version="1.1" will return:

"Program: Ladder Author: g964 Phone: +1-503-555-0090 Date: 2019-01-01 Version: 1.1"

Rules:

• The date should always be "2019-01-01".

• The author should always be "g964".

• Replace the current "Program Title" with the prog argument supplied to your function. Also remove "Title", so in the example case "Program Title: Primes" becomes "Program: Ladder".

• Remove the lines containing "Corporation" and "Level" completely.

• Phone numbers and versions must be in valid formats.

A valid version in the input string data is one or more digits followed by a dot, followed by one or more digits. So 0.6, 5.4, 14.275 and 1.99 are all valid, but versions like .6, 5, 14.2.7 and 1.9.9 are invalid.

A valid input phone format is +1-xxx-xxx-xxxx, where each x is a digit.

• If the phone or version format is not valid, return "ERROR: VERSION or PHONE".

• If the version format is valid and the version is anything other than 2.0, replace it with the version parameter supplied to your function. If it’s 2.0, don’t modify it.

• If the phone number is valid, replace it with "+1-503-555-0090".

Note

• You can see other examples in the "Sample tests".
