9 Algorithm
Take out N of these numbers from 1-N + 1, and ask which one is left. .
I said adding up and subtracting, but the interviewer said it was a trick.
When I said comparing array subscripts, he still said to be tricky.
So I asked him to remind me, he said to sort and then look for it. . amount
Then I thought of two ways to change space for time, one is to use hashmap to traverse two arrays. One is the number of occurrences of statistics after merging the arrays, which is also a hashmap
Given a string of numbers, find all possible IP address combinations, such as 192168111, the combination is 192.168.1.11, 192.168.11.1.
It should be LeetCode's question. I didn't write it completely before, and it came out on the spot.
This code should be correct. The interviewer watched for twenty minutes before saying ok.
Then we were silent for 20 minutes, and he said a few words in the middle.
