Your company assigns each customer a membership ID, and you are implementing a check digit for those IDs.
The check digit should be calculated by adding up all digits in each membership ID. If the result of the sum is a number with more than a single digit, another iteration is required, and the digits of the result also should be added together. This process should repeat until a single-digit number is calculated.
For example, for the membership ID "55555" the sum of all digits is 25. Because this is not a single-digit number, 2 and 5 would be added, and the result, 7, would be the check digit.
- Example case: Wrong answer
- Single iteration required: Wrong answer
- Two iterations required: Wrong answer
- Multiple iterations required: Wrong answer

Screening Applicants: The Good, the Bad and the Ugly
Since we’re all biased and we use incorrect proxies, why not just outsource hiring to experts or recruitment agencies? After all, they’ve been screening people for many years, so they must know how to do it right?
Not really. I was surprised to discover that many experts disagree with each other. Everybody praises their pet method and criticizes the others. Many of these methods look legitimate, but are based on...
