在时间间隔列表中查找时间间隔之间的最大持续时间

def find_max_duration(intervals):
    intervals.sort(key=lambda x: x[0])  # 按照起始时间排序
    max_duration = 0
    prev_end = float('-inf')  # 上一个时间间隔的结束时间

    for interval in intervals:
        start, end = interval
        if start > prev_end:
            duration = end - start
            max_duration = max(max_duration, duration)
        else:
            duration = end - prev_end
            max_duration = max(max_duration, duration)
        prev_end = end

    return max_duration
