  • you are not using “exact” phrasing in your “closing announcement”

Status: CLOSED QUARTER: $0 DIME: $0 NICKEL: $0 PENNY: $0.5

  • in your attempt you are showing them in different order and without “$” sign

i noticed in other use cases you used “$” in them but not for last test case!! may be addressing that would resolve it!!

happy coding :slight_smile:

tried many ways dont know what to do.

maybe share those snippets in turn and explain behind those attempts, maybe that way you will find an answer to that!!

given that if you again look into output string for: price 3.26 and cash 100 use case you will are getting correct output
Status: OPEN Change: TWENTY: $60,TEN: $20,FIVE: $15,ONE: $1,QUARTER: $0.5,DIME: $0.2,PENNY: $0.04

but for last use case you are returning this string instead!!

which is totally different!!

trace this back, and maybe look into logic where this is being constructed…

happy coding :slight_smile:
