1893. Check if All the Integers in a Range Are Covered

Leetcode Solutions

Initialize an array line with a length sufficient to cover the entire number line we are interested in (in this case, up to 51, since the problem constraints go up to 50).
Iterate over each range in ranges and update the line array by incrementing the value at the start index of the range and decrementing the value right after the end index of the range.
Initialize a variable overlaps to keep track of the number of overlapping ranges at each point.
Iterate through the line array from index 1 to right, updating overlaps by adding the current value of line at each index.
If at any point from left to right (inclusive) the overlaps value is zero, return false as that point is not covered by any range.
If we reach the end of the iteration without finding an uncovered point, return true.
