    Easy way to figure out what a regex means is to just plug it into regex101 (though this one appears to have problems, `[0|+[0-9]` matches 0 to 9, or a pipe, or a plus) – CertainPerformance Jun 18 '19 at 06:20
  • I am not aware about regex101 , thanks for suggestion – shivani Jun 18 '19 at 06:22
