count-carry-problem-6

Regional Students's are taught to add multi-digit numbers from right-to-left one digit at a time.
Many find the "carry" operation - in which 1 is carried from one digit position
to be added to the next - to be a significant challenge.  Your job is to
count the number of carry operations for each of addition problem so that educators may assess their difficulty.

For the input first line contains n number of records which is less then 1000. And then each line contains two numbers with spacing between them as shown in sample. 

SAMPLE INPUT
3
123 456
555 555
123 594

SAMPLE OUTPUT
No carry operation
3 carry operations
1 carry operation

Explanation

EXAMPLE 1:-

when the digits are added then there is no carry found as 3+6=9,2+5=7 and 1+4=5.

EXAMPLE 2:-

when the digits are added then carry is generated as 5+5 =10 so carry is found 3 times.

EXAMPLE 3:-

when the digits 9 and 2 are added only then carry is found so 1 time only.
