Errors detected during execution are called exceptions.
This error is raised when the second argument of a division or modulo operation is zero.
This error is raised when a built-in operation or function receives an argument that has the right type but an inappropriate value.
The statements try and except can be used to handle selected exceptions. A try statement may have more than one except clause to specify handlers for different exceptions.
Error Code: integer division or modulo by zero.
You are given two values a and b.
Perform integer division and print a/b.
The first line contains T, the number of test cases.
The next T lines each contain the space separated values of a and b.
Print the value of a/b.
In the case of ZeroDivisionError or ValueError, print the error code.
For integer division in Python 3 use //.
