Number Theory blocks [mathematics]

Number Theory Blocks

Number Theory blocks are also very important (dalao says Mobius will be used in the future)

 

Typical Chestnuts:ForI = 1 ~ N evaluate Σ x = (N/I) (Note: Here () represents the rounded down)

Ordinary people are generally violent and complex O (N)

Number Theory blocks are used here.

We can simulate that X remains unchanged within a certain range.

Here we can use parts. Calculate the left endpoint and right endpoint of each piece with the same value, and then sum the result of the arithmetic difference series.

 

This is only an entry-level application of number theory. It will be completed later...
