Removing first and last digits from and interger

Write a function that, given an integer \(N1\), returns another integer \(N2\) that is the result of removing the first and last digit of \(N1\). Note: If \(N1\) has 2 digits or only one, then \(N2\) must be 0. Examples of test cases that you can automate with pytest are:

testcase number input (\(N1\)) expected output (\(N2\))
1 42635 263
2 23 0
3 5 0
4 0 0
5 -3456 -45 
Insist that the students test their programs by giving them a table
of test cases.
