将两组区间组合成一组区间

def merge_intervals(intervals):
    intervals.sort(key=lambda x: x[0])  # 按照起始点升序排序
    merged = []  # 存储合并后的区间结果

    for interval in intervals:
        if not merged or interval[0] > merged[-1][1]:
            # 当前区间与结果列表中的区间没有重叠
            merged.append(interval)
        else:
            # 当前区间与结果列表中的区间存在重叠，进行合并
            merged[-1][1] = max(merged[-1][1], interval[1])

    return merged

# 示例输入
intervals1 = [[1, 3], [2, 6], [8, 10], [15, 18]]
intervals2 = [[2, 5], [7, 9], [11, 13], [14, 17]]
intervals = intervals1 + intervals2

# 合并区间
merged_intervals = merge_intervals(intervals)

# 输出合并后的区间
for interval in merged_intervals:
    print(interval)

[1, 6]
[7, 10]
[11, 13]
[14, 18]
