Hello codeforces, hope you all doing well.

Today I was upsolving Vowel Anxiety of Codechef Starters 46.

I got wrong answer on all test case files except one. I tried to find the test case using Debug feature of Codechef but it didnt showed any test cases. It told that : "Unable to find test case, please try again in some time"

Is it bug from codechef or just in my laptop?

I have attached the ss below for proof :

Codechef Admin and others please look into it.

Thanks and stay healthy.
