Interval Overlaps

You are given a list of intervals where each interval is represented as a pair of integers [start, end]. Write a program that determines if any of the intervals overlap with at least one other interval. An interval [a, b] overlaps with another interval [c, d] if and only if a <= d and c <= b. Print 'Yes' if any overlaps exist, otherwise print 'No'. Input format: - The first line contains an integer n, the number of intervals. - The next n lines each contain two integers, start and end, separated by a space. Output format: - Print 'Yes' or 'No'. Example: Input: 3 1 3 2 4 5 7 Output: Yes
