Star Shorthand

Published by Matt in

Write a function that converts a string into star shorthand. If a character is repeated n times, convert it into character*n.

Examples

toStarShorthand("abbccc") ➞ "ab*2c*3"

toStarShorthand("77777geff") ➞ "7*5gef*2"

toStarShorthand("abc") ➞ "abc"

toStarShorthand("") ➞ ""

Notes

  • Leave lone occurrences of a character as is.
  • Return an empty string if given an empty string input.
