Problem type

Luke (perhaps Skywalker) is a passionate computer science student. He receives as homework the following task:

Given a sequence of $N$ ~N~ integers, determine if the subsequence from $x$ ~x~ to $y$ ~y~ inclusive is a Great Sequence. A Great Sequence is a sequence whose sum is strictly greater than $K$ ~K~.

Luke thought this is too easy, so he has thought up a new challenge: he'd like to know if a subsequence is an Amazing Sequence. An Amazing Sequence is a Great Sequence in which the integers $a$ ~a~ and $b$ ~b~ appear. Given his original sequence, he'd like to answer $Q$ ~Q~ queries, determining if a subsequence is an Amazing Sequence.

Constraints

For all subtasks:

$-10^9 \le K \le 10^9$ ~-10^9 \le K \le 10^9~

$-1\,000 \le a_i, b_i \le 1\,000$ ~-1\,000 \le a_i, b_i \le 1\,000~

$1 \le x_i \le y_i \le N$ ~1 \le x_i \le y_i \le N~

Subtask 1 [30%]

$N \le 1\,000$ ~N \le 1\,000~

$Q \le 1\,000$ ~Q \le 1\,000~

Subtask 2 [70%]

$2 \le N \le 10^5$ ~2 \le N \le 10^5~

$1 \le Q \le 10^5$ ~1 \le Q \le 10^5~

Input Specification

The first line of input will contain the space-separated integers $N$ ~N~, $K$ ~K~ and $Q$ ~Q~. The second line of input will contain $N$ ~N~ space-separated integers representing the sequence. For the last $Q$ ~Q~ lines, line $i$ ~i~ will contain query $i$ ~i~ in the format $a_i$ ~a_i~, $b_i$ ~b_i~, $x_i$ ~x_i~ and $y_i$ ~y_i~.

Output Specification

For each query, print Yes if the subsequence is an Amazing Sequence, No otherwise.

Dropped time limit to 0.2s to kill vectorized cheese.

What is wrong with my program? Second subtask passes
