Beautiful Subsequence

CodeChefRating 2937Open on judge ↗

Consider a sequence with an even length $2L$. A *left rotation* consists of moving the first element of the sequence to the end. The sequence is *good* if it is possible to perform some number of left rotations (possibly zero) and divide the resulting sequence into two halves (containing the first $L$ and last $L$ elements respectively) such that the smallest value in one half is greater then the
