    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 <code>rangesi = start<sub>i</sub>, end<sub>i</sub></code> represents an inclusive interval between <code>start<sub>i</sub></code> and <code>end<sub>i</sub></code>.

    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 <code>rangesi = start<sub>i</sub>, end<sub>i</sub></code> if <code>start<sub>i</sub><= x <= end<sub>i</sub></code>.

    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 &lt;= ranges.length &lt;= 50

    • <code>1 <= start<sub>i</sub><= end<sub>i</sub><= 50</code>

    • 1 &lt;= left &lt;= right &lt;= 50
