This probelm has a `pattern` you need to find,and when you did it would look like something like this:\n```\nint countVowelStrings(int n) {\n        return ((n+1)*(n+2)*(n+3)*(n+4))/24;\n    }\n```\nIf you have any questions drop them below \uD83D\uDC47 and if liked it ,kindly  **Upvote** it \u2B06
