The interview process starts with an HR recruiter call.

This call will discuss your interests and help determine the best group or team for you.

Your recruiter will also use this conversation to confirm your potential fit for the role.

You should be prepared to explain your background and why you're a good fit for Microsoft.

Given an array of characters, chars, compress it using the following algorithm:

Begin with an empty string s.

For each group of consecutive repeating characters in chars:

• If the group's length is 1, append the character to s.
• Otherwise, append the character followed by the group's length.

The compressed string s should not be returned separately, but instead be stored in the input character array chars.

Note that group lengths that are 10 or longer will be split into multiple characters in chars.

After you are done modifying the input array, return the new length of the array.
