CHEFSQ- wrong solution accepted

[abhichal_18]

This question is from beginner section. It is accepting the wrong solution according to me. As my code accepted and it is showing yes for
1
6
1 2 4 3 5 6
3
2 3 4

as the question says favourite sequence should be present as a substring but it is accepting for presence of the elements in the normal sequence

Chef and Sequence giving wrong answer (CHEFSQ)

Ugh - it’s an unbelievably sloppily-written question, but looking at some of the AC submissions, it appears that the elements of F need not be consecutive in N i.e. we need to check whether F is a subsequence of N, in spite of the question asking to check whether it is a substring. (sigh). For example, a randomly-chosen AC solution gives Yes for the testcase: 1 8 1 2 3 8 8 5 6 5 4 1 3 5 5 ( 1 2 3 8 8 5 6 5 ^ ^ ^ ^ )

Edit:

Oh, I see what you mean: your solution doesn’t even check that it is a subsequence, but still gets AC. I guess we can add “weak testcases” to the list of flaws of that Problelm
