Correct answer will be upvoted else downvoted. Computer science. lamp can be coordinated to enlighten either a few lights to the left or a few lamps to the right. In the event that the I-th lamp is gone to one side, it enlightens all such lights j that j∈[i−pi,i−1]. Also, in case it is gone to one side, it enlightens all such lamps j that j∈[i+1,i+pi]. You will probably pick a course for every light so every lamp is enlightened by undoubtedly another lamp, or report that it is incomprehensible. Input The primary line contains one integer t (1≤t≤10000) — the number of experiments. Each experiment comprises of two lines. The primary line contains one integer n (2≤n≤3⋅105) — the number of lamps. The subsequent line contains n integers p1,p2,… ,pn (0≤pi≤n) — the force of the I-th lamp. The amount of n over all experiments doesn't surpass 3⋅105. Output For each experiment, print the appropriate response as follows: In case it is feasible to coordinate all lamps…
