Try breaking it down into manageable steps:

  • create a new empty string and a new number as a sum with a value of 0
  • use a loop to go though the items of the list
  • for each item, if it's a string, concatenate it to the new string
  • if it's a number, add it to the new sum
  • after the loop ends, convert the sum to a string and concatenate it to the new string
  • then return the new string
