# Introduction | ||
|
||
You've joined LinkLine, a leading communications company working to ensure reliable connections for everyone. | ||
The team faces a big challenge: users submit phone numbers in all sorts of formats — dashes, spaces, dots, parentheses, and even prefixes. | ||
Some numbers are valid, while others are impossible to use. | ||
|
||
Your mission is to turn this chaos into order. | ||
You'll clean up valid numbers, formatting them appropriately for use in the system. | ||
At the same time, you'll identify and filter out any invalid entries. | ||
|
||
The success of LinkLine's operations depends on your ability to separate the useful from the unusable. | ||
Are you ready to take on the challenge and keep the connections running smoothly? |
