Given A and B two interval lists, A has no overlap inside A and B has no overlap inside B. Write the function to merge two interval lists, output the result with no overlap. Ask for a very efficient solution
For example,
A: [1,5], [10,14], [16,18]
B: [2,6], [8,10], [11,20]
output [1,6], [8, 20]
Facebook也考过这题。
注意：OCI的招聘流程简直是乱得一批啊，电话面试鸽了我3次，面试官一直说自己特别忙，一会儿再赶项目，一会儿在开会，最后经理出来面的。印度公司不值得！
