Chef has a sequence of ๐‘N integers, ๐ด1,๐ด2,...,๐ด๐‘A 1โ€‹ ,A 2โ€‹ ,...,A Nโ€‹ . He likes this sequence if it contains a subsequence of ๐‘€M integers, ๐ต1,๐ต2,...,๐ต๐‘€B 1โ€‹ ,B 2โ€‹ ,...,B Mโ€‹ within it. A subsequence is a sequence that can be derived from another sequence by deleting some or no elements without changing the order of the remaining elements.You will be given a sequence of ๐‘N integers, ๐ด1,๐ด2,...,๐ด๐‘A 1โ€‹ ,A 2โ€‹ ,...,A Nโ€‹ followed by another sequence of ๐‘€M integers, ๐ต1,๐ต2,...,๐ต๐‘€B 1โ€‹ ,B 2โ€‹ ,...,B Mโ€‹ .

The subsequence is present at indices 1,2,31,2,3 of the original sequence. Hence, 1,2,3,4,5,61,2,3,4,5,6 is a sequence which Chef likes it. Therefore, we output "Yes".In sample test case 22, the subsequence 4,154,15 is not present in sequence 22,5,6,33,1,422,5,6,33,1,4.

Chef has an array ๐ดA of size ๐‘N. He wants to make a permutationโ€ โ€  using this array.Find whether there exists an array ๐ตB consisting of ๐‘N non-negative integers, such that the array ๐ถC constructed as ๐ถ๐‘–=๐ด๐‘–+๐ต๐‘–C iโ€‹ =A iโ€‹ +B iโ€‹ is a permutation.โ€ โ€  A permutation of size ๐‘N is an array of ๐‘N distinct elements in the range [1,๐‘][1,N]. For example, [4,2,1,3][4,2,1,3] is a permutation of size 44, while [3,2,2,1][3,2,2,1] and [1,3,4][1,3,4] are not.Input FormatThe first line of input will contain a single integer ๐‘‡T, denoting the number of test cases.Each test case consists of multiple lines of input.The first line of each test case consists of ๐‘N - the size of the array ๐ดAThe next line contains ๐‘N space-separated integers - ๐ด1,๐ด2,โ€ฆ,๐ด๐‘A 1โ€‹ ,A 2โ€‹ ,โ€ฆ,A Nโ€‹ - the elements of array ๐ดA.Output FormatFor each test case, output YES if there exists an array ๐ตB such that array ๐ถC constructed as ๐ถ๐‘–=๐ด๐‘–+๐ต๐‘–C iโ€‹ =A iโ€‹ +B iโ€‹ is a permutation, otherwise output NO.You may print each character of the string in uppercase or lowercase (for example, the strings YES, yEs, yes, and yeS will all be treated as identical).Constraints1โ‰ค๐‘‡โ‰ค1001โ‰คTโ‰ค1001โ‰ค๐‘โ‰ค1001โ‰คNโ‰ค1001โ‰ค๐ด๐‘–โ‰ค๐‘1โ‰คA iโ€‹ โ‰คNSample 1:InputOutput454 1 3 2 152 4 3 4 21161 1 1 1 6 6YESNOYESNOExplanation:Test case 11 : Consider ๐ต=[0,4,0,0,0]B=[0,4,0,0,0].
