public final class Solution1893 - Check if All the Integers in a Range Are Covered.
Easy
You are given a 2D integer array
rangesand two integersleftandright. 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
trueif each integer in the inclusive range[left, right]is covered by at least one interval inranges. Returnfalseotherwise.An integer
xis 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 <= ranges.length <= 50<code>1 <= start<sub>i</sub><= end<sub>i</sub><= 50</code>
1 <= left <= right <= 50
