//Introduction
// Your task in order to complete this Kata is to write a function which formats a duration, given as a number of seconds, in a human-friendly way.
// The function must accept a non-negative integer. If it is zero, it just returns "now". Otherwise, the duration is expressed as a combination of years, days, hours, minutes and seconds.
// It is much easier to understand with an example:

// formatDuration(62)    // returns "1 minute and 2 seconds"
// formatDuration(3662)  // returns "1 hour, 1 minute and 2 seconds"
// For the purpose of this Kata, a year is 365 days and a day is 24 hours.

// Note that spaces are important.

//Introduction
// Your task is to sort a given string. Each word in the string will contain a single number. This number is the position the word should have in the result.
// Note: Numbers can be from 1 to 9. So 1 will be the first word (not 0).
// If the input string is empty, return an empty string. The words in the input String will only contain valid consecutive numbers.

//Examples
// "is2 Thi1s T4est 3a"  -->  "Thi1s is2 3a T4est"
// "4of Fo1r pe6ople g3ood th5e the2"  -->  "Fo1r the2 g3ood 4of th5e pe6ople"
// ""  -->  ""
