1893 - Check if All the Integers in a Range Are Covered\.
Easy
You are given a 2D integer array `ranges` and two integers `left` and `right`. Each ranges[i] = [starti, endi] represents an **inclusive** interval between starti and endi.
Return `true` _if each integer in the inclusive range_ `[left, right]` _is covered by **at least one** interval in_ `ranges`. Return `false` _otherwise_.
An integer `x` is covered by an interval ranges[i] = [starti, endi] if starti <= x <= endi.
**Example 1:**
**Input:** ranges = \[\[1,2],[3,4],[5,6]], left = 2, right = 5
**Output:** true
**Explanation:** Every integer between 2 and 5 is covered:
- 2 is covered by the first range.
- 3 and 4 are covered by the second range.
- 5 is covered by the third range.
**Example 2:**
**Input:** ranges = \[\[1,10],[10,20]], left = 21, right = 21
**Output:** false
**Explanation:** 21 is not covered by any range.
**Constraints:**
* `1 <= ranges.length <= 50`
* 1 <= starti <= endi <= 50
* `1 <= left <= right <= 50`
