Approach

Find pattern

• people separator is ';'

• name separator is ':'

• must be ordered by 'last name, first name'

Solve the problem

1. split by person name ';'

2. split to first and last name based on process-1 result

3. sort by last name, first name

4. formatting to (${lastName}, ${firstName})

5. join names

Solution

JavaScript

// Meeting
// https://www.codewars.com/kata/59df2f8f08c6cec835000012

const meeting = (s) => s.toUpperCase()
  .split(';')
  .map((v) => v.split(':').reverse())
  .sort((a, b) => {
    if (a[0] === b[0]) {
      return a[1].localeCompare(b[1]);
    }
    return a[0].localeCompare(b[0]);
  })
  .map(([lastName, firstName]) => `(${lastName}, ${firstName})`)
  .join('');
