Vladik had started reading a complicated book about algorithms containing n pages. To improve understanding of what is written, his friends advised him to read pages in some order given by permutation P = [p_1, p_2, ..., p_{n}], where p_{i} denotes the number of page that should be read i-th in turn.

Sometimes Vladik’s mom sorted some subsegment of permutation P from position l to position r inclusive, because she loves the order. For every of such sorting Vladik knows number x — what index of page in permutation he should read. He is wondered if the page, which he will read after sorting, has changed. In other words, has p_{x} changed? After every sorting Vladik return permutation to initial state, so you can assume that each sorting is independent from each other.


-----Input-----

First line contains two space-separated integers n, m (1 ≤ n, m ≤ 10^4) — length of permutation and number of times Vladik's mom sorted some subsegment of the book.

Second line contains n space-separated integers p_1, p_2, ..., p_{n} (1 ≤ p_{i} ≤ n) — permutation P. Note that elements in permutation are distinct.

Each of the next m lines contains three space-separated integers l_{i}, r_{i}, x_{i} (1 ≤ l_{i} ≤ x_{i} ≤ r_{i} ≤ n) — left and right borders of sorted subsegment in i-th sorting and position that is interesting to Vladik.


-----Output-----

For each mom’s sorting on it’s own line print "Yes", if page which is interesting to Vladik hasn't changed, or "No" otherwise.


-----Examples-----
Input
5 5
5 4 3 2 1
1 5 3
1 3 1
2 4 3
4 4 4
2 5 3

Output
Yes
No
Yes
Yes
No

Input
6 5
1 4 3 2 5 6
2 4 3
1 6 2
4 5 4
1 3 3
2 6 3

Output
Yes
No
Yes
No
Yes



-----Note-----

Explanation of first test case:   [1, 2, 3, 4, 5] — permutation after sorting, 3-rd element hasn’t changed, so answer is "Yes".  [3, 4, 5, 2, 1] — permutation after sorting, 1-st element has changed, so answer is "No".  [5, 2, 3, 4, 1] — permutation after sorting, 3-rd element hasn’t changed, so answer is "Yes".  [5, 4, 3, 2, 1] — permutation after sorting, 4-th element hasn’t changed, so answer is "Yes".  [5, 1, 2, 3, 4] — permutation after sorting, 3-rd element has changed, so answer is "No".
