RANGZER2 - ZEROES IN RANGE V2
You are given two integers a and b. Find the number of zeroes in the digits of all the numbers in the range [a,b] inclusive.
The first line consists of an integer t, the number of test cases. For each test case you will be given two integers a and b (a<=b).
For each test case print the required answer.
We yet have such problem (or very near), and here constraints are too weak. Should be moved to tutorial.
