Interval Gaps

Given a list of intervals [start, end], find the gaps between the end of one interval and the start of the next one, when the intervals are sorted by their starting times. A gap is defined as the difference between the end of one interval and the start of the next interval when the end is less than the start. Input format: - The first line contains an integer n (1 ≤ n ≤ 100): number of intervals. - The next n lines each contain two integers start and end, separated by a space (0 ≤ start < end ≤ 10^9). Output format: - Print the gaps in ascending order, each gap on a new line. If there are no gaps, print 'No Gaps'. Example: Input: 3 1 3 4 5 7 8 Output: 1 2
