extends Object

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`
