Baidu interview question objective answer [original], original interview question answer
Recently, I have been looking for a job. I often send interviews with some big companies in the class group to test the questions. I received such a question yesterday, which is said to be Baidu's interview question.

wooden pole, each of which has an ant in the five positions 3 cm, 7 cm, 11 cm, 17 cm. The wooden pole is very small and cannot pass through an ant at the same time. At the beginning, the head of the Ant Financial system is either left or right. they only move forward or turn their heads, but do not move back. When any two ants meet, they both turn their heads to the opposite direction. It is assumed that the Ant Financial can walk 1 cm away every sec

approach to handle the amount of memory used will depend on your program's requirements. using a profiler may give you suggestions for where to optimize code by showing which parts of your program are using the most memory.
Memory counters:
By default, ants memory profiler uses the private bytes counter, because this measure is considered the most useful for most kinds of memory problem.

First, the discussion1. Algorithm sourceThe basic principle of ant colony algorithm originates from the principle of the shortest path of ants foraging in nature, according to the observation of the insect, it is found that the ant of nature is not developed visually, but it can find the shortest path from food source to nest without any hint, and can change the environment (if there are obstacles on the original path). Adaptively search for the new b

It is known that n kinds of ingredients need to be removed, and these ingredients form a circle from 1 to N in turn. The little ant has a value VI for each of the ingredients, of course, if VI is less than 0, it means the ant hates the ingredients. Becau
When it comes to ant in English, people naturally think of ants. When it comes to another word make, people naturally think about building tools. Who would associate these two words with each other? So what's so weird about ant? This article will reveal the answer to you.

Question:The length of the tunnel is l, the number of ants is N, the position pI of each ant, and the forward direction di are all integers (forward direction is L or R), and the ant speed is 1cm per second, if the two ants encounter each other at an integer point, they both return to the opposite direction. If they do not encounter an integer point, they continue to move forward.
There are two ways to optimize the system: optimization algorithms and code writing.
Optimization Algorithms often increase efficiency much more than code optimization. However, algorithm optimization depends on a person's familiarity with system algorithms,
If a person is not familiar with the system, and then needs to optimize the system (is this a bit awkward? Khan ...), What should I do.
In other words, if you want to focus on the implementation of the system and determine the problems to be
