Given that "userInput.match$($regular expression$)"$ is the function to check if the userInput match the regular expression or not and its return value is null when not matching.

Given that "userInput.length" is the length of the user input.

Write $"$if$-$else" statements to check if the user input meet each requirement or not.

You can use integer array a$=[]$ to store the comparison results, so the sum of the comparison results can be used as a unique number to reflect if the user input met the requirements or not.
