1450 - Number of Students Doing Homework at a Given Time\.
Easy
Given two integer arrays `startTime` and `endTime` and given an integer `queryTime`.
The `ith` student started doing their homework at the time `startTime[i]` and finished it at time `endTime[i]`.
Return _the number of students_ doing their homework at time `queryTime`. More formally, return the number of students where `queryTime` lays in the interval `[startTime[i], endTime[i]]` inclusive.
**Example 1:**
**Input:** startTime = [1,2,3], endTime = [3,2,7], queryTime = 4
**Output:** 1
**Explanation:** We have 3 students where:
The first student started doing homework at time 1 and finished at time 3 and wasn't doing anything at time 4.
The second student started doing homework at time 2 and finished at time 2 and also wasn't doing anything at time 4.
The third student started doing homework at time 3 and finished at time 7 and was the only student doing homework at time 4.
**Example 2:**
**Input:** startTime = [4], endTime = [4], queryTime = 4
**Output:** 1
**Explanation:** The only student was doing their homework at the queryTime.
**Constraints:**
* `startTime.length == endTime.length`
* `1 <= startTime.length <= 100`
* `1 <= startTime[i] <= endTime[i] <= 1000`
* `1 <= queryTime <= 1000`
