Exceptions

Errors detected during execution are called exceptions.

Examples:

ZeroDivisionError 

This error is raised when the second argument of a division or modulo operation is zero.

>>> a = '1'
>>> b = '0'
>>> print int(a) / int(b)
>>> ZeroDivisionError: integer division or modulo by zero

ValueError 

This error is raised when a built-in operation or function receives an argument that has the right type but an inappropriate value. 

>>> a = '1'
>>> b = '#'
>>> print int(a) / int(b)
>>> ValueError: invalid literal for int() with base 10: '#'

Handling Exceptions

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.

#Code
try:
    print 1/0
except ZeroDivisionError as e:
    print "Error Code:",e

Output

Error Code: integer division or modulo by zero

Task

You are given two values $\boldsymbol{\alpha}$ and $\boldsymbol{b}$. 

Perform integer division and print $a/b$. 

Input Format

The first line contains $\mathbf{T}$, the number of test cases. 

The next $\mathbf{T}$ lines each contain the space separated values of $\boldsymbol{\alpha}$ and $\boldsymbol{b}$.

Constraints

$0<T<10$

Output Format

Print the value of $a/b$. 

In the case of ZeroDivisionError or ValueError, print the error code.

Sample Input
3
1 0
2 $
3 1

Sample Output
Error Code: integer division or modulo by zero
Error Code: invalid literal for int() with base 10: '$'
3
