OJ question of sequence table

One ：

 

1： First time to know Leetcod, When doing problems, you must remember to draw pictures , Indicate the initial value of variables and the relationship between variables ;

2： The size of the sequence table data is larger than the coordinates of the data 1;

3： Calculate the process of each cycle in the figure ;

Two ：

1： This question is most likely to miss many situations , And the determination of the boundary range ;

2:  There are two situations in the cycle , There are two ways ;

3： After exiting the loop, there are two different situations and two different ways ;

4; Application 3 Each pointer records its position ; a key ; Multiple pointers solve the problem ;

3、 ... and ：

1：  In short, in the process of writing questions, we must pay attention to clarify whether there are many situations ; Then sort out the basic process of a cycle ;

Different situations will be solved in different ways ;

2： Skillfully use multiple pointers to try to solve the problem ;

3： Pay attention to drawing drawing drawing ;
