# Primary Arithmetic
|
||
|
|
|
||
|
|
Children are taught to add multi-digit numbers from right to left, one digit at a time.
|
||
|
|
Many find the “carry” operation, wherea 1 is carried from one digit position to the next, to be a significant challenge.
|
||
|
|
|
||
|
|
Your job is to count the number of carry operations for each of a set of addition problems so that educators may assess their difficulty.
|
||
|
|
|
||
|
|
## Details
|
||
|
|
|
||
|
|
Write a **carryOperations** function.
|
||
|
|
The function has the following parameters:
|
||
|
|
- **num1**: first integer to sum
|
||
|
|
- **num2**: second integer to sum
|
||
|
|
|
||
|
|
Returns:
|
||
|
|
- Number of carry operations as an integer
|
||
|
|
|
||
|
|
## Constraints
|
||
|
|
- Input parameters are unsigned integers less than 10 digits.
|
||
|
|
|
||
|
|
|
||
|
|
### Example
|
||
|
|
```text
|
||
|
|
carryOperations(123, 456) ➞ 0
|
||
|
|
carryOperations(555, 555) ➞ 3
|
||
|
|
carryOperations(123, 594) ➞ 1
|
||
|
|
carryOperations(555, 545) ➞ 3
|
||
|
|
carryOperations(1, 20000) ➞ 0
|
||
|
|
carryOperations(1, 2) ➞ 0
|
||
|
|
```
