Please grammar check the questions prior to the contest. English is my second language so poor grammar makes it incredibly difficult, if not impossible, for me to understand the question. Thank you!
I understand what you're saying. I found some of the questions very confusing but this question was not so bad.
But i had to read multiple times this line :
"Also given an integer k, you need to output in which day there exists two flowers in the status of blooming, and also the number of flowers between them is k and these flowers are not blooming."
