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`
