Summer camp -8.10 summary

Learning content : basic knowledge of mathematics fight cattle off +

The completion of the number of questions today (does not include multi-school) : 6

Today's reading situations : 10

 

Today's experience:

       You can use reverse thinking, in turn, do consider the question.

       Some things look since the time complexity is about the same, but in fact is a lot of difference,

       For example, elements of a vector to delete the time complexity is O (N), and the set of

      The time complexity is O (logN). Bottom of things enough to understand.
