<p>You are given an integer <code>n</code> denoting the total number of servers and a <strong>2D</strong> <strong>0-indexed </strong>integer array <code>logs</code>, where <code>logs[i] = [server_id, time]</code> denotes that the server with id <code>server_id</code> received a request at time <code>time</code>.</p>
|
||
|
|
|
||
|
|
<p>You are also given an integer <code>x</code> and a <strong>0-indexed</strong> integer array <code>queries</code>.</p>
|
||
|
|
|
||
|
|
<p>Return <em>a <strong>0-indexed</strong> integer array</em> <code>arr</code> <em>of length</em> <code>queries.length</code> <em>where</em> <code>arr[i]</code> <em>represents the number of servers that <strong>did not receive</strong> any requests during the time interval</em> <code>[queries[i] - x, queries[i]]</code>.</p>
|
||
|
|
|
||
|
|
<p>Note that the time intervals are inclusive.</p>

<p><strong class="example">Example 1:</strong></p>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
<strong>Input:</strong> n = 3, logs = [[1,3],[2,6],[1,5]], x = 5, queries = [10,11]
|
||
|
|
<strong>Output:</strong> [1,2]
|
||
|
|
<strong>Explanation:</strong>
|
||
|
|
For queries[0]: The servers with ids 1 and 2 get requests in the duration of [5, 10]. Hence, only server 3 gets zero requests.
|
||
|
|
For queries[1]: Only the server with id 2 gets a request in duration of [6,11]. Hence, the servers with ids 1 and 3 are the only servers that do not receive any requests during that time period.

<p><strong class="example">Example 2:</strong></p>

|
|

|
|
<pre>
|
||
|
|
<strong>Input:</strong> n = 3, logs = [[2,4],[2,1],[1,2],[3,1]], x = 2, queries = [3,4]
|
||
|
|
<strong>Output:</strong> [0,1]
|
||
|
|
<strong>Explanation:</strong>
|
||
|
|
For queries[0]: All servers get at least one request in the duration of [1, 3].
|
||
|
|
For queries[1]: Only server with id 3 gets no request in the duration [2,4].
